Burning smell from Ghostbusters Premium pinball. Game is turned off for me and when I get back to investigate about 45 min later, I can smell under playfield the burning odor but can't find the culprit. So what do I do? I am running it now, but for about 10min but no smell develops. Here is some other odd things. I noticed that the Scolari brothers targets during game play pretty much constantly tick while in down position from the relay coil that lets the target drop. They pulse/tick. Also I noticed there are like no fuses in this game other then 2 fuses I noticed on what I guess is are 2 LED's boards. Magnets do not have fuses. I recall The Addams family not having them and a fuse kit was used to save the magnets from burning the playfield. Could that happen here in the future?
Edit: All lights, flashers and coils seem to work when put in test.

I was not around to diagnose, that would have been ideal. Now I can not reproduce the smell.

So far, I have changed both flipper coils and disconnected both magnets. No issues so far. I am waiting for the magnet kit to have both magnets fused. Edit: Kits arrived, magnets fused with 3amp fuses. No issues. Must have been a bad flipper coil.
