Quoted from BRW84:I'm trying to fix a Gottlieb Genie for a friend and I'm beating my brains out. The lower right flipper and the upper right flipper won't activate. I've put new diodes on the coils and replaced the bridge rectifier for the solenoids, but no luck. It has a new-ish MPU and driver board, so I'm fairly confident the problem isn't there. Does anyone know what I should check next? Thanks!
Is this a new to you game or did they just stop working? Did you check the right flipper switch? Compare the voltage to the left side one with a meter. Some of games had soldered on wires on the flipper switches and others had crimped connectors. The crimped ones will fail over time and need some attention.
