Charging System

The charging system provides electrical current for the lights, radio, heater blower and the engine’s electrical systems. It also maintains the batteries in a charged state, recharging them as necessary to provide cranking power.

The charging system has three main components, or component areas: the alternator, the voltage regulator, and the battery.

The alternator is driven by a belt from the engine crankshaft and produces the electrical power to operate the systems on the bus. It also recharges the battery.

The voltage regulator acts as a “control valve” for the alternator output. It senses the current load and maintains a constant voltage in the charging system, independent of the current load, up to its rated output. The alternator on the Blue Bird All

American has a “built in” voltage regulator as standard equipment. A remote regulator is available as an option. They are self excited (started) alternators.

The battery is the reservoir of chemical electrical power. Its primary purpose is to crank the engine. It also supplies power to the accessories for a short time when the demand is too high for the alternator alone (i.e., while the bus is at idle). Another key role of the battery is to act as a filter for the charging system by providing clean

“electronic power” for the electronic control systems; ECU, ECM, TCM, and gauges.

Maintenance

Clean the alternator and all connection points. Dirt buildup restricting air flow through to the alternator will cause excessive heat and premature failure. Corrosion at any connecting point will produce resistance to current flow, heat and diminished power for the accessories.

Ensure that all the components in the charging system are mounted securely.

Check the torque at all mounting bolts — both the bolts that hold the alternator in the mounting bracket and the bolts that secure the mounting brackets to the engine.

The torque value for mounting bolts at the engine should be 70 - 80 ft. lbs. for a L/N and 55 - 59 ft. lbs. for a Bosch.

Blue Bird All American buses are equipped with an automatic belt tensioner. Ensure that all the grooves fit properly into the pulleys in the correct path. The drive belt should be inspected per the schedule in the maintenance chart located in the Specs

and Maintenance chapter of this manual.

Also check:

• Battery voltage

• Alternator output

• Starter current draw

Troubleshooting

Timely preventive maintenance of the charging system should keep it running smoothly. However, when a problem occurs, effective troubleshooting procedures will help locate and correct the problem quickly and economically.

[Warning]

Batteries emit an explosive gas. Never smoke while working on the charging system. Batteries can explode from a spark. Always remove the negative battery cable at the battery post before removing any other wires in the charging system. Be careful not to short the system while you are working on it. Do not wear jewelry.

Before you begin to analyze the charging system, it is necessary that you ensure the battery is properly tested and charged to at least 75% of their rated capacity. Failure to confirm the condition of the battery will make the results of any diagnostic testing unreliable. Refer to the battery manufacturer’s publications on battery maintenance and testing.

Alternator Performance Test

1. Connect a digital volt/ohmmeter (VOM) to the output terminals of the alternator.

[Caution]

Ensure that the test leads are connected properly. Observe the polarity and make secure connections.

2. Connect an ammeter to the positive terminal of the alternator. Observe that the clamp on the ammeter is located at least 6 inches (15 cm) from the alternator to lessen the possibility of faulty readings due to spurious emissions.

3. Verify that the voltage output from the alternator is between 13.8 and 14.2 volts with the engine at operating

RPM (1700 RPM minimum) and not idle.

4. Ensure that all “loads” are in the off position. The reading on the ammeter should be less than 20 amps.

• If the amp reading is higher than 20 amps, ensure all accessories are turned off.

• Ensure the battery is charged to at least 75% of their rated capacity.

5. Record the voltage. If the voltage is not within the specified range or the amperage is not within the specified range, the alternator is defective.

SERVICE MANUAL chASSIS ElEctrIcAl

6. If the alternator is determined to be defective, repair or replace it in accordance with the instructions below. See Alternator removal.

7. If the alternator is determined to be functioning properly, proceed as follows:

8. Continue to operate the engine at about 1700 RPM, and with the test equipment set up as illustrated.

9. Turn on vehicle loads (accessories) until the ammeter displays amps, 75% of the rated capacity of the alternator. Record the voltage at this point.

10. compare the voltage reading with the voltage reading observed in Step 3 above.

11. If the alternator voltage drops more than .5 (1/2) volt, the alternator is defective.

An alternate method of checking the alternator under load is to use a carbon pile load. Connect the carbon pile across the battery and adjust it until the ammeter reads 75% of the alternator rated capacity. Record the voltage at this point, shut off the engine, and compare the readings.

Alternator Cable Tests

To test the positive alternator cable:

1. Clamp the ammeter on the positive cable at least 6 inches (15 cm) from the alternator. See Figure 2.

2. Connect the negative lead of the VOM to the positive post of the alternator.

3. Connect the positive lead of the VOM to the positive battery post.

4. Start the engine and let it run at about 1700 rPM.

5. Turn on accessories until the ammeter reads amps, which is 75% of the rated alternator capacity, Use a carbon pile if necessary to achieve the load.

6. Record the voltage reading on the VOM.

7. If the VOM reads more than -.25 volts, there is a problem with the positive cable.

• check and clean all the connections and the condition of all the cables/wires in the circuit.

• re-test the circuit.

8. If the reading is less than -.25 volts, the cable and connections are good.

9. Connect the negative lead of the VOM to the negative terminal of the battery.

10. Connect the positive lead of the VOM to the negative terminal of the alternator.

11. repeat Steps 4 through 8 for the negative cable.

Alternator Removal

[Warning]

Always disconnect the negative (-) cable from the battery terminal first to avoid arcing, which could ignite explosive battery gases.

1. Park the bus on a smooth, flat surface.

2. Chock the wheels in both directions.

3. Ensure the engine is not running, the ignition switch is in the “OFF” position and the key is removed.

4. Disconnect the negative (ground) cable from the battery post.

5. Using a square drive tool, position the automatic tensioner so that the drive belt can be removed.

6. Remove the drive belt.

7. Inspect the drive belt; discard it if any signs of wear are present.

A few minor cracks across the belt are acceptable. Longitudinal cracks are NOT acceptable. Replace the drive belt when any crack is observed to be running lengthwise or with the belt, or when the belt appears frayed.

[Warning]

Always disconnect the negative (-) battery cable at the battery before removing any wiring from the alternator.

8. Remove the negative (-) cable from the alternator.

9. Remove the positive (+) cable from the alternator.

10. Support the alternator and remove the mounting bolts.

Automatic Belt Tensioner

The automatic tensioner is spring loaded to provide the proper tension for the drive belt.

The automatic tensioner should travel freely within its full range of travel. Inspect the belt tensioner for any unusual noise, excessive loosenenss and shaking at the bearings.

Automatic Tensioner Removal

1. Remove the drive belt in accordance with the instructions above.

2. Remove the bolt from the automatic tensioner.

To install a new automatic tensioner, reverse the removal instructions.

L


Starter

There are 5 main components or component areas in the starting system: the ignition switch, a neutral safety switch, the starter solenoid, the starter motor and the batteries.

When the key is turned to the start position, electrical current flows to the starter solenoid from the batteries. The flow is interrupted if the transmission shift lever is not in the neutral position or if the neutral sensor switch is defective.

The starter solenoid is an electromagnetic switch mounted on the starter motor.

When electric current energizes coils inside the solenoid, a magnetic field is induced which pulls a plunger. At one end of this plunger is a lever. The lever is connected to the starter drive pinion of the starter motor. The plunger also connects the electrical power from the batteries to the starter motor as the drive pinion engages the flywheel ring gear.

The starter motor is a relatively small electric motor, but it can deliver large amounts of torque for a short time.

When the operator releases the ignition switch it returns to the run position. The solenoid is disconnected from the batteries and the magnetic field collapses. This allows the spring in the solenoid to move the plunger in the opposite direction, disengaging the drive pinion from the flywheel and removing electrical current from the starter motor.

The Blue Bird All American has a 12-volt electrical system.

Preventative Maintenance

There are two preventative maintenance procedures that can greatly enhance the efficiency of the starting system. These two steps are also the first two steps taken when troubleshooting a malfunctioning starting system.

• An engine that needs a tune up will be difficult to crank; over cranking will lead to starter motor failure.

• Poor connections due to road dirt, grease, corrosion, loose connectors, or broken insulation at any connecting point rob the starting system of electrical power and cause it to over-crank.

705

L

SERVICE MANUAL

706

Troubleshooting

Before beginning to troubleshoot the starting system, ensure the batteries are properly maintained and charged to at least 75% of their rated capacity. A drained battery will cause any further diagnostic tests to be inaccurate. Common causes of starting system malfunction include:

1. A battery that is low, poorly charged, or defective places high demands on the starting system; voltage at the battery should be 12.6 to indicate a fully charged battery. If the batteries aren’t adequately charging, a problem in the charging system. refer to the Alternator section of this Service Manual for information on the charging system.

2. A starter motor can be damaged by heat that is generated by excessive cranking. The starter should never be engaged for more than 30 seconds. It must “rest” (cool off) a minimum of 2 minutes between starting attempts.

3. Loose, dirty, or corroded connections in the starting system rob the system of the power needed to turn the engine. The case of the starter motor is the ground or “return” connection for the starter motor and solenoid.

4. A loose starter motor will allow vibration that can damage the motor. In addition, the ring gear could be damaged.

5. A defective solenoid will fail to engage the starter drive pinion of the starter motor. A failed pull-in coil will cause the plunger to fail to pull in. A failed hold-in coil may cause the starter to fail to stay engaged, or may fail to switch the starter motor on. If the solinoid is suspect, test the wiring of the solenoid circuit before replacing the solenoid.

[Warning]

DO NOT use starting fluid as an aid to starting the engine. This could cause an explosion resulting in personal injury or death.

L


Ignition/Run Test

Begin by determining whether the problem is with the ignition switch or the pilot relay, and their associated wiring; or if it is in the solenoid and/or starting motor. To begin with the ignition switch:

1. Connect the positive lead of a VOM to the ignition switch terminal on the solenoid.

2. Connect the negative lead of the VOM to the chassis ground.

3. While attempting to crank the engine, record the voltage displayed on the VOM. Observe the following:

• No voltage

• low voltage

• Normal voltage with slow cranking

• Normal voltage with no cranking at all.

4. Connect a remote start switch to the positive battery post.

5. Connect the other end of the remote start switch to the ignition post of the solenoid.

6. Attempt to crank the engine with the remote switch. Record the voltage displayed on the VOM. If there is less than 1 volt difference from the previous reading, the ignition switch is okay. If there is more than 1 volt difference, the switch is defective.

7. With the VOM negative lead connected to the chassis ground, move through the switch system one connection at a time. If your first voltage test has revealed low voltage, the starter motor may be shorted.

8. If the first voltage test indicated normal voltage, but there is slow cranking or no cranking at all, a problem with the batteries, battery cables, or a damaged starter motor is indicated.

Low Voltage Test

There are various reasons for low voltage but the troubleshooting methods are the same. If the solenoid clicks, it means that either current is flowing through the solenoid contacts but not through the main contacts; or that the current through the main contacts is insufficient due to low batteries.

1. Connect the positive lead of the VOM to the starter motor terminal of the solenoid.

2. Connect the negative lead of the VOM to the chassis ground.

3. While attempting to crank the engine, if there is no voltage displayed on the VOM, the main contacts are not functioning properly.

4. If there is voltage present at the solenoid terminal during Step 3, the problem is in the starter motor or its cabling.

5. If the first voltage check in Step 3 under Ignition/run test indicated normal voltage but slow or no cranking, the next step is to check the starter motor and its connections.

6. If the drive pinion jumps out of mesh with the flywheel ring gear, check for a broken or loose ground wire at the solenoid.

7. While attempting to crank the engine, place an ammeter on the positive battery cable. If the power drain is higher than the OEM specifications, the starter motor is defective. An exception would be if the engine was not properly tuned or is difficult to turn over; in which case, a new starter motor would be a temporary fix.

Slow Cranking

Sluggish cranking can be caused by a small amount of extra resistance in the cranking circuit. This extra resistance can come from loose or dirty (corroded) connections, or broken wires and/or cables. First check the positive cables and connections of the starter motor, then the negative circuit.

1. Connect the positive lead of a VOM to the positive battery terminal.

2. Position an ammeter between the solenoid and the positive terminal of the solenoid.

3. Connect the negative lead of the VOM to the positive terminal of the solenoid.

4. Connect the negative lead of the VOM to the negative battery post. This is the “unloaded” voltage. Record the reading; leave the VOM connected.

5. Connect one lead of a carbon pile tester to chassis ground.

6. Connect the other lead from the carbon pile tester to the positive terminal of the solenoid.

7. Adjust the carbon pile tester until the ammeter on the tester reads 500 amps.

8. Record the voltage display on the VOM; it should not be less than 0.4-volts less than the unloaded value.

9. Turn the carbon pile tester to the “OFF” position.

10. Connect the positive lead of the VOM to chassis ground.

11. Connect the negative lead of the VOM to the negative battery post. Record the reading; leave the VOM connected.

12. Position the ammeter in on the negative battery cable.

13. Turn on the carbon pile tester and adjust it to read 500 amps.

14. Record the voltage on the VOM; standard guidelines state it should not drop more than 0.5-volts from the unloaded reading. Depending on electrical options installed on the bus voltage drop may be more.

15. Turn the carbon pile tester to the OFF position.

16. If the voltage drop was more than 0.5-volts (depending on options) in step

8, the positive cabling is defective. Look for a broken cable or a loose or corroded connection.

17. If the voltage drop in step 14 is more than 0.4 volts, look for a problem in the negative cabling; look for broken or defective cables, and loose or corroded connections.

Final check at solenoid terminals.

1. Disconnect the carbon pile tester.

2. Disconnect the VOM.

3. Remove the ammeter.

4. Connect the positive lead of the VOM to the positive (battery) terminal of the solenoid.

5. Set the VOM so that it can read the full battery volt-age; at least 14 volts.

6. Connect the negative VOM lead to the starter motor terminal of the solenoid.

7. Crank the engine and record the voltage while cranking. There should be no more than 0.2 volts drop between the solenoid contacts while cranking.

8. The voltage reading in these last three tests (the positive cable check, the negative cable check and the solenoid test), should not total more than 1.0 volts. If the voltage drop is more than allowable, repeat the cable tests using a jumper cable. If the tests then indicate an acceptable drop, the cable(s) is

(are) defective.

Chassis Wiring Schematics

The D3 All American electrical diagrams are formatted by electrical system, electrical circuit, or by options/features. They are also divided into two basic groups, body and chassis electrical systems. There are some over lapping circuits resulting in some body circuits existing on chassis diagrams and some chassis circuits existing on body diagrams.

Each circuit is represented on the diagram with its own line running from one connector to another connector or from a connector to an electrical source or electrical load. When a dot is encountered on a circuit line it indicates a soldered splice with all the circuits that intersect that point. Each circuit will be identified by a number or the description of the circuit, the color of the circuit and the gauge of the wire used in the circuit is also indicated on the diagram. In some cases the circuit will be identifed as positive (+) or negative (-). Most of the circuits interface the electrical system through electrical connectors. Each half of the connector will be identified with the letter “P” or “J” and a number. The two halves of the connector may or may not have the same number code but each half will be clearly marked on the print. Each pin in the connector will be indentified with a letter or number, the male and female side of the connector will be indicated and each circuit flowing through a connector will have a description. Information concerning the continuation of a circuit that exists on more than one diagram will also be provided, (example; See Diagram WrG: Power and Ground).

Some of the diagrams are subdivided by dotted lines that usually run through the center of a connector. The subdivisions represent the different electrical harnesses making up the circuits on a specific diagram. This provides the interaction between electrical circuits or harnesses and serves as a general locator for the electrical connectors.

The following subdivisions are identified on the drawings:

ELEC PANEL – Side (Body) Electrical Panel, located in the access panel below the driver’s side window. It serves as the main power distribution point for the body electrical system. The Body Control Module (BCM) is also located in the side body electrical panel.

PDU – Power Distribution Unit, located in the lower access panel below the driver’s side window. It serves as the main power distribution point for the chassis electrical system. Power from the battery is routed through the PDU before being distributed to the upper electrical panel and throughout the bus.

DCM – Driver Control Module, represents the structural support for the dash, the steering column, left side of the fire wall, and the structure the driver seat is fastened to. With respect to electrical diagrams, this subdivision could represent any electrical circuit or device in and around the drivers area, including circuits routed to the steering column, heaters and etc. These circuits will interface with the PDU, the body electrical panel, the engine harness and the transmission harness.

ENGINE – This subdivision involves all electrical circuit interfaces between Blue Bird systems and the engine electrical system, mainly the engine ECU. This does not include the engine wiring harness supplied with the engine.

PDU Access

Electrical Panel Access

713

L

SERVICE MANUAL

714

TRANSMISSION – This subdivision involves all electrical circuit interfaces between

Blue Bird systems and the transmission electrical system.

IP – Instrument Panel, involves all electrical interfaces between the instrument panel and Blue Bird’s electrical system.

FRAME – This subdivision involves the electrical circuits located on the frame and circuits not covered by other subdivisions.

BODY - This subdivision involves the electrical circuits located on the body and circuits not covered by other subdivisions.

For example, on diagram D0001451 - AIr ABS SYStEM, even though the ABS system is for the most part a self contain electrical system the circuits between the ABS EcU/

Modulator and the other ABS components are routed through six separate electrical subdivisions indicated on the drawing. Starting at the top right corner and working around the print clockwise the PDU provides power to the ABS system. From the lower right corner across the bottom and up through the center of the diagram the diagram provides most of the electrical interface between the ABS components and the rest of the electrical system. Other electrical interfaces on the diagram include the Transmission, the DCM, Instrument Panel, and Electrical Panel along the left side of the diagram.

The following pages contain the main wiring schematics applicable to most All

American chassis. These are provided for your convenience when you are limited to use of the print manual.

The drawings on the CD are in resolution-independent vector format. This allows you to zoom them at will, without the images becomming jagged as occurs with bitmap formats. This also means that you may print the drawing to your own office or desktop printer while maintaining legibility even at significant reductions.

For more information see; About the TechReference CD; Electrical Schematics located in the Introduction section of Volume 1. Also see additional wiring schematics for your bus at the Customer Access web site:
