I'm helping a friend w/ his Grand Lizard and I'm very much a hobbiest newbie. Recently all of the solenoids (except flippers) quit working. The 2.5A fuse was blown. A replacement fuse blew again immediately. Prior to this, the game was running fine after replacing all lights to LEDs, new rubbers, etc... Tonight I checked every transistor for each solenoid and the smaller transistor that drives the bigger one. All looked normal in that the readings were mostly similar to each other. I also checked (and replaced) all diodes on the 7 solenoids. Old diodes checked out fine but I put in new ones while there.
What next? I'm not sure what I'm missing and not sure what to look at next. Any tips? I did find a leg on a diode disconnected on a EOS switch on the right flipper but can't see how that's related.
