I am new to the pinball world and recently picked up a FPII and it’s worked great for the last few months. However, I accidentally left it on for about 15 hours.
I can start a new game (ball gets kicked up to the plunger and games score correctly. However, flippers, pop bumpers, and sling solenoids will not fire (ball lock eject does work). I have 60ish volts on the flippers and 30v on the other solenoids.All fuses check OK and I reseated all driver board connectors.
The only other symptom I can determine is the board diagnostics says error “9” which corresponds to an issue the the coin door, memory protect fault, or IC19. DMM says Coins door works and game seems to remember settings. So I think this might be a red herring.
Anyone have an idea on what I can check next? Maybe a ground someplace or header to reflow?
Edit: I reviewed the device manual in more detail. It looks like the attached connector is suspect. I’ll reflow here. Any idea where ground is returned?
