Ok, I got the GI lights all working on the LW3, I got it to stop blowing fuses, now the left and right kicker are not working, they do not turn on when you turn the game on, but as soon as you start a game, the right one locks on the left one does nothing, Even if I go into diagonistics the second I do that right kicker fires and stays locked on. I changed Q12, no difference.. anyone have thoughts?
Thanks

Are the switches for them working properly in switch test? If you ground the tab on the drive transistor for the left one does it fire? If the switches are working properly and the right one is not stuck closed I'd guess the pre-driver transistor is the culprit there, you could disconnect the coil and test with a meter to determine if that's the case or not.

I did short out the transistor, and the left side did fire, however the right side is stuck on, also the laser kick back is not working, and that coil was roasted, the auto launch is not firing either.. This one has been a FUN project.. taking the MPU and PPB boards to be tested tomorrow.
