Strangeways, thanks for the reply.

I tested all the coils with a DMM and they are ok.

I tested the transistors on the CPU (one end on the tab of the transistor and the other on the ground strap) and I think Q9 is bad. Do you think replacing this would be a good place to start?

As I said, several solenoids are locked on at power up - some flashers, the knocker and maybe some others, I didn't leave the game on long enough to get a good look. Is there a safe way to test what is locking on when the game is powered on?
