The trough up-kicker, the auto launch and both pop bumpers stop working, in play and in coil test, so a game starts but no ball is served. Fuses look good.
Trough kicker, auto launch and both pop bumpers dead: broken daisy-chain wire
Cause: These coils share a power wire that is daisy-chained from coil to coil. It had come unsoldered at one of the pop bumper coils, cutting power to everything after it.
Checks
- Pull the fuse for that coil group and test it out of circuit.
- Find the wire colour the dead coils share and follow it from coil to coil, checking each lug.
Fix
- Resolder the loose wire at the coil lug.
