C h a S S i S E... Charging System

C h a ss i s E l ec t r i c a l
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. It is excited (started) by the ignition system.
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 and at the alternator should be
60 – 70 ft lb.
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 every 11,000 miles (17,700 km), 250 hours of service life, or
every 3 months; whichever occurs first.

• 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.
Digital Volt/Ohm Meter
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.
820
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.

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:
Digital Volt/Ohm Meter
1. Clamp the ammeter on the positive cable at least 6
inches (15 cm) from the alternator. See Figure 2.
821
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.
Ammeter
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.
L
service manual
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.
Volt/Ohm Meter
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.

Automatic Belt Tensioner
The automatic tensioner is spring loaded to provide the proper tension for the drive
belt.
The automatic tensioner should travel at least 71º, and the torque to move the
tensioner 25º from the “at rest” position must be 9 – 11 ft lb (12.4 – 15.8 Nm). Inspect the belt tensioner for any unusual noise, excessive looseness and shaking at
the bearings.
Automatic Tensioner Removal
1. Remove the drive belt in accordance with the instruc-tions above.
2. Remove the capscrew (1) from the automatic ten-sioner. See Figure 8.
To install a new automatic tensioner, reverse the removal instructions. Torque the
capscrew (1) to 28 – 42 ft lb (38 – 56 Nm).

service manual
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.
826
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.
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 12.5 volts or greater to
crank the engine. 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.
L
chassis electrical
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. Improper or excessive use of starting fluid will cause extra stress on the starting system.
6. 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.

service manual
Volt/Ohm Meter
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.
828
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.
Volt/Ohm Meter
Solenoid
1. Connect the positive lead of the VOM to the starter motor terminal

2. Connect the negative lead of the VOM to the chassis ground.
Alternator
Starter
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.
830
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; it should not drop more than 0.5-volts from
the unloaded reading.

15. Turn the carbon pile tester to the OFF position.
16. If the voltage drop was more than 0.5-volts 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.

831
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 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. However, the Tech Reference CD contains a duplicate set
of these drawings which provides additional functionality to aid navigation while
tracing circuits. When using the CD, click the Electrical Schematics Chassis link in the
Bookmarks pane. The first page of the Chassis Electrical Schematics group contains
instructions on how to use the linking and navigation features.
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.
