This has just started happening on my Mata Hari. Everything works as it should except when I put a quarter in to get a credit it just continues to give credits. I have to turn the machine off to get it to stop. Once I turn the game back on it's fine, I hit start and play as normal. I did a continuity test on the coin switch and they seem to be working correctly. I've look at the schematic and I can't determine the path of the credit switches. I'm assuming this could be a bad capacitor on the mpu?
