The thumper bumpers on my space invaders are dead. Traced the wire got good continuity back to the solenoid driver. Solenoid driver tested good in another machine. No power to the coils! It acts as if there is a missing/ bad fuse but i cannot find one. When I ground the tp102 on the board I get nothing. The (4)flippers, slingshots and ball return solenoids work normal. Is there something simple I am missing? Looking for a fresh set of eyes on this problem as I have been looking at it for a while. All of the test points are withing range on the driver and MPU.
