Yet another JP.
Left/Right motor not working during start up tests or during gameplay. Can only hear the relay click. Up/Down motor works just fine. Eats the ball just fine. Oh and game is running 5.01 software too.
So far:
- Motor tests good with a 9v battery applied.
- Reflowed relay board that controls Left/Right motor
- Replaced Q24 and its predriver (Drives Left/Right motor)
- Replaced Q27 and its predriver (Drives Bi-Directional Relay controlling voltage polarity for Left/Right motor)
Reading over the theory of operation service bulletin, says to check fuse F1 on the shaker board. 99% sure I checked it already but will check one more time when I get home. Other than that, I dont have a clue.
