Ok, fixed the flipper opto board problem....now on to the next issue (aren't pinball machines fun!)

When I hit the ball launch button, the right flipper flips. If I continue to play the game the right flipper fuse 901 on the fliptronics board eventually blows. I tested the switches in switch edge test and they are fine. Also tested the flippers in solenoid test and they are fine. I thought I figured it out when I found a flipper diode that was bad on the right coil, but after I replaced the coil, it is still doing it. Any ideas? I checked all the switches in that column with the launch button switch and they all look ok...nothing grounded. So what do ya think.....besides throw the Demo Man out the window....which I'm almost ready to do!! hahaha!!!

Thanks!!

You are right on the money!!! I JUST figured this out about 20 minutes ago! I hooked the old flipper optic board up and had no issues with the flipper flipping while hitting the launch button. Swapped out the GLM board for another one and it worked ok, then the launch button started making the flipper flip again.....moved the magnet a little bit away from the launch coil and BINGO! No more flipper activating! Good call!! Glad to see even if I didn't figure it out, I would have after reading this! Thanks for the reply!!!

P.S. The cause of the 901 fuse blowing was due to a bad flipper diode. Unrelated to this problem, but it looked like it was since it was happening to the right flipper.

I hope that's the last problem I need to fix with this thing!!!

Thanks!!
