The lower and upper right flippers both stop working, while the left flipper and other flippers still work. Fuses check good.
Both right flippers dead, left works: wire at a coil lug not making contact
Cause: The two right flippers share wiring. A wire on the upper right flipper coil lug looked attached but was no longer making contact, breaking the circuit for both.
Checks
- Check for voltage at both right flipper coils with the game on.
- Jumper the right cabinet flipper switch to test it.
- Pull back the sleeves on the coil lugs and look closely; a wire can hang by a thread or have a dry joint.
- Check the header pins and flipper relay solder joints on the driver board.
Fix
- Fully desolder the suspect wire from the coil lug, clean it and resolder it properly.
