Help me Obi Wan..

This f**king Frankenstein is doing my swede in at the moment.

I've sorted the display again, after it blew up the pi.

Now the ball won't eject into the trough, and when i go into the tests and test the flashers the coils fire like in ball search.


Bad BR?? Any ideas?

Diode?

Im not sure if its fuse F7 on the playfield power board as that controls the coils/flashers.

There's a relay on the driver board that switches between flashers and coils. That is not operating so the coils fire instead of the flashers. You need to check the feed / circuit for the relay. It's on the bottom left of the board, next to the big caps. There is a connector between that and the caps which may be the cause of the problem... try reflowing the connector pins as a starter for 10.

Good luck!
