The upper right flipper locked on and the coil burned out. A new coil worked for a few games and then the same thing happened.
Upper right flipper locked on and burned its coil: loose wire on the EOS switch
Cause: A wire had come loose on that flipper's EOS switch.
Checks
- Upper flippers here are switched through the lower flipper's button and the flipper relay, not a transistor, so look at the wiring and switches.
- Check every solder joint on the EOS switch and coil lugs.
Fix
- Resolder the loose EOS wire and replace the burned coil.
