POWER SUPPLY DIAGNOSTICS
1.) Verify AC power to game. Check power strip in bottom front.
2.) Check connection to power supply.
3.) Ensure Power Supply switch is set to 115V (or 230V)
(Some model power supplies may not have this)
4.) Ensure Power switch is on.
5.) Ensure fan is turning.
- If power supply fan is turning and there is no 12 Volt out, then replace power supply. (A5PS1008)
- If power supply fan is not turning, then continue to "Verify Power to Motherboard"
Verify Power to Motherboard
The motherboard will turn on power supply.
If your game has no 12 volts, it may be the motherboard not turning on.
In addition - there may be a 12 volt short somewhere else in cabinet that is not allowing the power supply to turn on.
Minimize load on power supply and isolate short
Unplug all outputs from power supply except for motherboard.
This will have power supply, motherboard, and monitor left plugged in.
If power supply, motherboard, and monitor now turn on:
Plug in one component at a time to power supply to
locate short.
If power supply still does not power on, then continue
to steps 1,2, and 3.
1 - Check BOTH connections from power supply.
Note: The location of this connector may vary depending on which ver-
sion motherboard is in game.
