Bought an MPU327-3 In May and finally have it installed in my Firepower. Game and diagnostics worked fine for a few days but now the left kicker (solenoid 22) is locked on but only when a game is started after pressing the start button. When the machine powers on, the coil isn't energized at all. Only when a game is started. When running the solenoid test in diagnostics mode, the coil locks on as well. The driver for the kicker, Q12, tests fine. Dropped the folks at Rottendog a message too but was wondering if anyone here might have had a similar problem or suggest somewhere to start? Thanks!
