INTRODUCTION
Power-line voltage has been standardized throughout the country at 115/230 volts, 60 hertz
(cycle), A.0 (alternating current) single phase. This figure represents nominal voltage and line
voltage in a particular area may be between 110 and 125 volts. Voltage average across the
country is approximately 117 volts. The domestic 82-70 pinspotter will operate satisfactorily
between 104 and 127 volts, 60 cycle. The foreign version 82-70 pinspotter operates on 50 hertz
(cycle) current. Either 115 or 230 volts.
Three wires are brought into the bowling centers distribution panel from the power company's
transformer. In the three-wire system, the third wire is neutral which is grounded. Voltage
between the other two wires is 230, while half of this voltage (115) appears between each of
these wires and neutral. In this system, pinspotter load is divided between the two sides of the
circuit, half the pinspotters in the center being connected between one wire and the neutral, while
the other half connected between the other wire and neutral.
Each pinspotter requires its own 25 AMP circuit breaker. The circuit breaker must be in the "hot"
side of the line going to the pinspotter. A 3-conductor power cord (Russell-Stoll plug) connects
the 115 volts to the pinspotter. Two of the conductors in this cord carry power, one hot and one
neutral or return. 115 volts can be measured between these two conductors. The third
conductor is connected to the frame of the machine, while having its other end connected to an
earth ground. This grounds the machine preventing the possibility of electrical shock. Power to
the machine and machine ground will only be present when the 3-contact polarized plug
(Russell-Stoll) is properly seated in its receptacle.
Some of the pinspotters' electrical components require 115 volts A.G. to operate and therefore
use the line voltage. Components using 115 volts include the table, sweep and back-end motors,
solenoids, pit light and 115 volts is applied to the primary transformer windings in the chassis.
Transformers are used to step-up (increase) line voltage or step-down (decrease) line voltage to
the level needed for relays, lights and other pinspotter controlling devices. Not all chassis used
on the 82-70 machine supply the same operating voltages. Voltage used to operate and control
the pinspotter might include 12, 24 and 115 A.G. (alternating current) and 5, -6.8, 10, 12 and 160 volts D.C. (direct current). The increased or decreased voltage will be present at the
transformer secondary winding but will always be A.C. Direct current (D.C.) is required for most
solid state devices and is obtained by using a rectifier to convert A.C. to D.C. Capacitor filtering
is used to remove any ripple from the rectified voltage.
Control voltage found at various machine switches will vary depending on the type of control
chassis being used. There will be 24 volts A.C. at some machine switches while -160 D.C. will
appear at others when a five board chassis is on the machine and that will change if a one board
replacement (XOP) is used. With an "A" or "B" chassis 24 volts A.C. and 24 volts D.C. will be at
the switches. 5 volts D.C. and 24 volts A.C. will be at the switches with an MP chassis.
Regardless of the voltage found there, the switches are used to control relays and/or chassis
logic to give the machine its sequence of operation.

The newer 82-70 Pinspotters (after 1979) have a stop switch located to the left of the power plug
on the front wireway of the machine. This safety switch, when pressed, turns off the machine
circuit breaker on the rear control panel. This disables all control circuitry, however power is still
in the pinspotter unless the power plug is removed.

MANAGERS CONTROL CIRCUIT
BOWL
When the managers control switch is moved into the bowl position, 24 volts A.C. are sent to one
side of the M relay coil. This voltage is available at the secondary winding of the T-2 transformer.
The circuit consists of the T-2 transformer secondary winding, managers control switch, masking
unit switch, and with some chassis, CB contacts A and B to the coil of the M relay. The other side
of the M relay coil is connected directly to the other side of the transformer winding. M now
becomes energized and its normally open contacts close, completing the necessary circuits to
turn the machine on.
INSTRUCT-O-MAT
When the managers control switch is moved into the Instruct-O-Mat position, the circuit is
completed in the same way as it was in the bowl position. In addition, the managers control circuit
is grounded. This ground prevents chassis logic from running the sweep down. The machine will
not go through its cycles until the managers switch is returned to the bowl position. However, the
back end motor will run normally with the managers switch in the Instruct-O-Mat (practice play)
position.

INTERLOCK
In order to energize the table or sweep motor relay, the 24 volt controlling voltage must pass
through the table sweep interlock circuit consisting of TB (table cam switch) and SC (sweep cam
switch) contacts wired in parallel. One of these switches, either TB or SC, must be on to run the
table and sweep motors. If the table and sweep are on a collision course, both TB and SC will turn
off. This removes the controlling voltage from both relays, stopping the table and sweep motors.
Table and sweep run switches are inoperative in an interlock condition. Cranking the table or
sweep motor to clear the interference zone is the safest procedure to follow.
INTERLOCK CIRCUIT
12
AMF BOWLING INC.
PINSPOTTER TRAINING
TABLE AND SWEEP CONTROL RELAY OPERATION
MOTOR RUNNING
On control relays T and S, two sets of contacts (normally open (N.O.) and normally closed (N.C.))
are used. For example, when S or T is energized, the normally open (N.O.) contacts close and
power is sent to the main winding and to the starting winding through the capacitors and
centrifugal switch starting the motor. When the motor gets up to speed, the centrifugal switch
opens, removing the start winding, and the motor continues to run on the main winding. If the
capacitors are in a charged state at this time, resistors connected in parallel with the capacitors
will discharge them. (Fig. 3)
MOTOR BRAKING
When T or S is de-energized, the normally closed (N.C.) contacts close, connecting the
capacitors across the main winding. When power is cut off to the motor, the armature still turning
acts as a generator and induces a voltage in the main winding. The capacitors connected in
parallel with the main winding provide a current path for the generated voltage, producing a
magnetic field. This magnetic field polarity opposes the rotating armatures magnetic field which
effectively slows down the motor. The motor slowing down closes the centrifugal switch
connecting the start winding across the main winding, producing additional field strength and
stopping the motor. When the armature has stopped turning, there is no more braking. Friction in
the motor's gearcase will hold the table and sweep at their zero positions. Some motors
incorporate friction braking in addition to regenerative braking to stop motors and hold them at
zero.

TESTING MOTOR PLUGS
A voltmeter or neon voltage tester can be used to check for voltage at the motor plugs. Voltage
will only be present at the plugs when the machine is on and the appropriate motor relay in the
chassis is energized. With the motor cable disconnected from the motor, look at the mating
surface of the plug. Table and sweep motor plugs are viewed with the index pin at nine o'clock
(Fig. 4.) Plug terminals can now be identified. The back end motor plug only has two terminals.
Voltage must be present between these two terminals when the back end relay is energized.
Voltage must be present between terminals X and NIL and between terminals X and Z of the
table and sweep motor plugs. In addition, there must be continuity between terminals Y and C.T.
Power must be removed from the pinspotter before making continuity tests. If voltage or
continuity is not present at the proper test points the motor cable plug can be disassembled and
connections inspected. Wires in the motor cable can be checked for continuity from the motor
plug to the terminal strip in the wireway. The C-I plug is another likely component to suspect
when motors fail to run or drift. Look for pins pushed in, burned or corroded. Terminal strip and CI plug numbers can be found on the 6730, 9807 or 5500 drawings. If voltage and continuity are
present at all the proper test points, but the motor fails to run, the motor itself may be at fault or a
motor capacitor may have failed. (See section on capacitor testing.)

USING A VOLTAGE TESTER
NOTE:
All power to the machine must be turned on. Do not touch exposed metal on test leads.
CAUTION Should be used when testing live circuits.
To check for voltage at the motor plug, the machine must be on and the motor relay must also be
on. Insert one test lead into each hole of the plug. (Fig. 5) If the neon lamp glows the circuit is
"hot"! If the neon lamp does not glow the circuit is open. The tester test leads do not have polarity
— either lead can be inserted into either hole.

MOTOR CAPACITORS
Two capacitors are used in the starting and electrical breaking circuits of the table and sweep
motors. Only one capacitor is used in the starting circuit of the back end motor. The back end
motor does not have a breaking circuit. Occasionally a capacitor may fail, resulting in an
inoperative motor. If a capacitor opens internally, the motor will not start. The motor will hum, get
hot and the klixon will trip. If a capacitor shorts internally, the motor will run but may start with a
strange sound. With a shorted capacitor, electrical braking will not work and the motor will coast
(drift) to a stop.
Burnt or loose connections may cause coasting or failure to run and the trouble could be
intermittent. Trouble areas include relay contacts, CI plug, motor plug and the centrifugal switch
in the motor. If the centrifugal switch is open, the motor will not start. The motor just hums, gets
hot and trips the klixon. If the centrifugal switch fails to open when the motor runs, once again the
motor gets hot. Also one or both capacitors may explode.
An ohmmeter can be used to determine if a capacitor is good, open or shorted. Capacitors store
an electrical charge and could be in a charged state in the machine. Before handling a capacitor,
remove the power plug (Russell Stoll), lift the cover from the wireway behind the table motor (Fig.
6) and short across the terminals of the capacitors. An insulated screwdriver can be used to do
this. If a capacitor is charged, this will discharge it. However, it is unlikely you will find a charged
capacitor in the pinspotter. The capacitors are identified as CTM for capacitor table motor and
CSM for capacitor sweep motor. The back end motor capacitor is mounted on the BE motor
stator.
To test a capacitor, after making certain it is discharged, remove the connections from one
capacitor terminal (Fig. 7). Using the highest resistance scale of an ohmmeter, connect the meter
leads to the two capacitor terminals and leave them connected of approximately one minute. The
battery in the meter will charge the capacitor. A resistance reading of 50,000 ohms or more
indicates a good capacitor. If the meter reads zero ohms, a shorted capacitor is indicated. No
reading at all (infinite) indicates an open capacitor. After testing a capacitor it should be
discharged by shorting across its terminals. When replacing a capacitor, it should be installed
with the vent plug at the top (12 o'clock position). Capacitor terminal screws must be tight. The
resistors to the right of the capacitors in the wireway are used to discharge the capacitors.

TROUBLE SHOOTING PROCEDURES FOR WIRING AND SWITCHES
Wires are used to connect individual circuit components, such as switches, lights,motors, and
control chassis. Wire used in the Pinspotter is called stranded wire. It is made up of individual
strands of wire, twisted together in a bundle and wrapped in insulation. Wires sometimes break at
stress points where they are twisted, subjected to continual bending, or just have normal use
over a long period of time. Normally, wire has very low resistance. When wires break or "open",
their resistance is very high or "infinite", and no current will flow. An open circuit test would
indicate a broken wire. In addition to an "open" wire causing trouble, wires "shorted" to other
wires or a wire "grounded" to the machine frame will cause trouble. Each condition, "open",
"shorted", or "grounded" requires a different test procedure in order to isolate the problem.
Testing for continuity, ("open" circuit test) is probably the most common test made. This test can
be used to check wires, switches, fuses, bulbs, relay contacts and many other electrical devices.
Any of the various types of continuity testers available can be used to make these tests.
However, continuity testers supply their own voltage to the circuit or device being tested. Make
ed." vi
•• •- • a "n the
circuit. Electricity can kill.
When a machine malfunctions and the cause is not obvious, the machine control chassis can be
replaced with a chassis known to be good, thus eliminating the chassis as a possible cause of
the problem. If changing the chassis cures the problem, we would then repair the chassis.
However, if the problem remains, we would trouble shoot the machine wiring and switches. What
the machine does or does not do dictates what circuit a problem is in and what type of test
should be used.
EXAMPLE:
If a pindication light never comes on, we would look for an open wire.
If a pindication light always comes on, we would look for a ground or short.
USING A CONTINUITY TESTER
A simple flashlight type continuity tester is easy to use. It consists of a flashlight with plug in test
leads. The test leads must be shorted together to make the light come on. To use the continuity
tester, turn it on and touch the leads together. The light should come on. Always perform this
preliminary step before using any continuity tester. it verifies that the tester is working.

Open Circuit Test
To check continuity of a wire, switch, fuse or relay contact, remove it from the circuit by
disconnecting one end of the wire or one wire from the switch. Connect one test lead to one end
of the suspected wire, and the remaining test lead to the other end of the disconnected wire. If
the wire is good, the tester will light. With an open wire, the tester will not light. When testing a
switch, it should be turned on and off several times to detect intermittent closings. (See Fig.8)
Short Circuit Test
To check for a short between two wires, disconnect both ends of the suspected wires. Connect
one test lead to each wire. If the tester lights, the wires are shorted to one another. If the tester
does not light, the wires are okay.
Ground Test
If a grounded wire is suspected, disconnect both ends of the wire, connect one test lead to the
frame of the machine. This connection should be made to unpainted metal. The other test lead
connects to the wire being tested. If the wire is grounded, the tester will light.

1. Connect continuity tester across common (C) and normally closed (N.C.) contacts of
switch. Tester should light. Depress button on switch several times to check mechanical
action. Tester light should go on and off.
2. Connect continuity tester across common (C) and normally open (N.O.) contacts of
switch. Tester should not light. Depress button on switch several times. Tester light should
go on and off.

HOW TO LOCATE BREAKS IN WIRES
If you have a wire that is broken (no continuity) a continuity tester will tell you the wire is broken,
but not where the break is. Here is one method that can be used to locate the break. The first test
would be over the entire length of the wire indicating a break (no continuity). An extension wire
can be used if the test leads are not long enough. Next, test from one end of the wire to a point
somewhere near the center. A pin can be used to pierce the insulation so contact is made with
the wire. If there is continuity perform the same test on the remaining length of the wire. if there is
no continuity, take half the length of the wire and repeat the test, Continue to use this half the
length of previous test approach until the break is found (see Fig. 9)

Plug viewed from mating surface with the 13
terminal row to your right.
With the mating surface of the plug held vertically and facing you, and with the outside row of 13
terminals to your left, the left column of 13 terminals is column 1 (Fig. 11). The next column to the right,
having 12 terminals, is column 2, the next is column 3 and the right-hand column, having 12 terminals,
is column 4. Starting at the top of the plug, the first pin in a column is pin 1. The next one below it is pin
2, the next is pin 3, etc. The last pin in column 1 is pin 13. The last pin in column 2 is pin 12. The
drawings are marked to indicate what plug is being used, e.g., Cl, C2A, table or A&MC. Numbers are
used to indicate the column and pin. The first digit of the number indicates the column, the second
digit(s) indicates the pin. Example: C2A 3 5 - this is the C2A plug, column 3, 5th pin down. C2A 311
would mean the C2A plug, column 3 11th pin down. Letters of the alphabet are also used at each
terminal for their identification. Example: C2A 11 B. The exact same method of numbering is
incorporated for the receptacle, except the receptacle columns are numbered from right to left (Fig. 12).
All AMP type "M" plugs and receptacles used on the pinspotter are read in a similar fashion.

If an open occurs in the GP switch, wire assy. or table cable, the table will not feel for pins
during the first ball cycle.
2.
Test - make sure respot cells are open, then connect jumper between (SW) contacts on
terminal strip. If table feels for pins, there is an open in this circuit. Visually check all plugs,
and connections, then test for continuity in the GP circuit and table cable.
3.
If the table does not feel for pins with the jumper in place, the open is between the chassis
(C) plugs and the terminal strip, or the problem is in the chassis, replace chassis and try
again.
NOTE:
The contacts on TAC terminal strip I thru 10 are wire connections coming from (GS) gripper switch
