So a few weeks ago I had a pop bumper (upper/bottom) coil burn up on my Ripley's. I replaced the fuse, transistor(Q11), diode, and coil, worked great. Then about 4 days later I had smoke coming out of the playfield with another burnt pop bumper coil, this time the upper right one. I guess its possible that coincidentally a neighboring pop bumper coil/transistor could burn up in a short amount of time but I'm wondering if it's actually something else in that coil group causing the transistors to fail. This machine has probably been powered on for 40 hours its entire life. Anybody have any ideas or experience with this issue?
Thanks

Did you ever get to the bottom of this? My Ripleys believe it or not burned up 2 upper pop bumpers in 3 days. After you replaced the parts, have they failed again?

Have you looked at where the bumper skirt contacts the spoon switch?
If it's misadjusted to where it stays closed, it would lock the coil on.
It could be adjusted fine, but dirty and that friction is causing it to stay closed and lock on the coil.

I would start by inspecting the spoon switch while activating the bumper skirt with your finger. If you do this while in the switch test mode, it should let you know if the switch is staying closed.

Doing this will point out the problem or eliminate the switch as the problem.
