SYMPTOM CAUSE REQUIRED ACTION
Blocked or faulty fan Fan located on power supply functions as an
exhaust fan. With power on, check airflow near
each fan to assure that nothing blocks airflow.
Faulty mechanical
partsTurn off power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if VGM has one)
over motor. Inspect for faulty or worn belts,
bearings, couplings, gears, etc.
Faulty Wheel Driver
Board1.  Inspect Wheel Driver Board under low-light
conditions. To indicate presence of AC from the
transformer the LED’s glow when voltage is
received. However, voltages or signals may not
be normal.
2.  Examine fuses and cables on Wheel Driver
Board. Replace bad fuses. Use digital voltmeter
to verify AC voltage between each fuse holder
and ground. You should measure approximately
25V. See Wiring Diagram.
3.  Use the 20-VAC setting on digital voltmeter to
measure DC voltage at motor. Do not move
steering wheel, drive belt, or motor while making
this measurement. Any reading indicates
unstable supply that may contain ripple or noise.
4.  Select the STEERING W HEEL TEST from the
Diagnostic Menu. Follow on-screen instructions
to verify operation of the wheel motor and
steering position sensor.
5.  Verify proper operation of Wheel Driver Board by
placing it in working VGM.
•  Sloppy, unpredictable or
ineffective steering
•  Video is present
•  Video Game Machine (VGM)
operates normally
Loose or worn drive
belt1.  Turn off power. Open dashboard. Support
steering wheel and remove outer mounting
screws. Remove metal shield (if VGM has one)
over motor. Inspect for faulty or worn belts,
bearings, couplings, gears, etc. Refer to the
Service section for complete instructions.
2.  If drive belt isn’t worn or damaged, check its
tightness.
• Inability to make a
transmission selection.
•  Video Game Machine (VGM)
operates normally.Improper DIP Switch
setting(s)1.    From the Diagnostics Menu, choose DIP
SWITCH TEST. Make sure DIP 1, SW 1 is set to
the OFF position.
WARNING
The Wheel Driver Board heatsink, power resistors, and other components may be very
hot. The DC Motor in the steering wheel may also be hot.

SYMPTOM CAUSE REQUIRED ACTION
Power problem Verify connection of AC Power to video monitor.
Inspect neck of CRT in dim light. Glowing
filament near CRT base confirms monitor circuits
receive power. However, voltages or signals may
not be normal
.
Faulty wiring 1.  Turn off game power. Verify that video signal and
Remote Adjustment Board connectors seat
properly on Video Monitor Board.
2.  Assure that no wires are caught on chassis or
mounting brackets.
Improper monitor
adjustmentsCheck BRIGHTNESS (intensity) and
CONTRAST are set above their minimum levels.
•  Monitor appears non-
functional
•  Audio is present
•  Video Game Machine (VGM)
controls operate normally
Faulty monitor
circuitry1.  Examine AC line fuse on Video Monitor Board. If
fuse is faulty, replace it with an identically rated
fuse.
2.  If the fuse is good, verify video monitor operates
correctly by placing it in a working VGM.
3.  If monitor is bad; Check monitor power supply.
4.  If the power supply is good, Check monitor
horizontal output transistor and related circuitry.
Improper components 1.  Verify circuit boards are correct for this game.
Labels on each board record manufacturers’
name, assembly number and hardware version.
2. Verify ROM instruction set is correct for this
game. Game set includes more than one ROM.
Label on each ROM records assembly number
and software version.
Faulty Circuit Board 1.  Allow game to load normally. Note and record
any error messages that occur during self-test.
2.  Press and hold TEST MODE switch inside coin
door to enter Menu System. Select Diagnostic
Menu from the Main Menu. Then select CPU
BOARD TEST. Conduct this test to check
operation of critical components.
3.  Turn off power.  Inspect CPU Board to ensure
JAMMA cable connector is fully seated onto the
mating edge connector of the CPU. Check all
other cable connectors for correct alignment and
continuity.
4.  Compare activity of LED’s on CPU with the CPU
Indicator Chart.
•  Graphic images from game
do not appear
• No audio
•  Power-up self-test runs
Power Problems1.  Turn on Power. Use 20-volt DC setting on digital
voltmeter to measure DC voltages present at
Power connector pins. Verify +5V source if it is
adjustable. Refer to Cabinet Wiring Diagram for
specific wiring information and voltage limits.
2.  Use 2-Volt AC setting on digital voltmeter to
measure DC voltages at Power Connector pins.
Any reading indicates the supply voltages are
unstable and may contain ripple or noise.

CAUTION
Do not remove or install any connector when power is turned on. Installation under
power will damage the circuit boards or ROM’s and void the warranty.
WARNING: HIGH VOLTAGE.
Video Game Machine (VGM) monitors 
generate and store potentially lethal high
voltages. 
Avoid touching any part of the monitor until power has been off for some time.
A picture tube can maintain a hazardous charge for up to several days. Only qualified
technicians should service monitors. Turn off the power, unplug the VGM and discharge
the CRT before attempting service. Even properly discharged tubes can revert to a
highly charged state, without reapplication of power.
WARNING
In normal operation, the monitor doesn’t require isolation from AC line voltage. During
bench servicing, you may need to operate the monitor outside the cabinet. If you do,
isolate the monitor from line voltage with an isolation transformer.
Typical Cutaway Rear View
CAUTION
Do not operate the monitor without its Remote Adjustment Board.
WARNING: HANDLE FLUORESCENT TUBE AND CRT WITH CARE.
If you drop a fluorescent tube or CRT and it breaks, it will implode! Shattered glass can
fly eight feet or more from the implosion.

Power ProblemsUse 20-volt DC setting on digital voltmeter to
measure DC voltages present at Power
connector pins. Verify +5V, -5V and +12V
sources. Refer to Cabinet Wiring Diagram for
specific wiring information and voltage limits.
Faulty or improper
speaker1.  Turn off power. Remove grilles and check
speakers. Verify that speakers are full range
(100 to 10,000 Hz response) and rated for at
least 20 watts. Woofers must be rated for at least
40 watts.
2.  Verify proper speaker operation by placing
speaker in question in a working VGM.
Faulty wiringMultiple-speaker installations: Check for
reversed wires at one speaker. Weak or low
frequencies and thin or hollow sound quality are
symptom of incorrectly phased speakers. Sound
tests may not detect this condition, but you can
hear it during operation.
•  Audio is distorted, muffled or
has missing frequencies.
Improper Setting Press and hold TEST MODE switch inside coin
door to enter Menu System. Select SOUND
TEST from Diagnostics Menu. Increase volume
as required. This test will verify some audio
