Playing Future Spa sometimes the 5k light at the kickout comes on with the 3k or 7k lights. I've changed out the lamp driver on the board for the 5k lamp. Didn't fix the problem. I've changed out the lamp board entirely with another one. I've even swapped out MPU boards (but using same game ROMs). None of those fixed the problem. I don't see anything obvious in the wiring or connectors. What have I missed?

You may have to repin the input connector for the lamp driver and replace the header pins.

More details...I seem to have narrowed down more specifics: the 5k kickback lamp comes on when the outlane gate (the mechanical gate) opens, and stays on as long as the gate remains open.

Found pinched wires (shorted) under a cable clamp. Fixed the problem.
