Got this game in an unknown shape. It was pretty rough shape started with the boards. Solenoids worked fine on the bench, which makes me believe it's not a board problem.
When I plugged the boards into the game initially the added fuse to the BR blew. Added a circuit breaker to it, and now F2 blows on power up. I narrowed the problem down to 2J11. All coils move freely and none were burnt up and frozen.
What's the best way to find the short? Do you start by testing and replacing all diodes the coils, or start with something else?
