Pressing credit starts a game and the score reels and bonus reset, but the outhole relay never pulls in, so no ball is served. Pushing the relay in by hand works.
Game resets but the outhole relay never fires: feed wire hanging by a strand
Cause: The wire that supplies power to the outhole relay coil was broken and hanging on by one or two strands.
Checks
- Before digging into the delay relay, bonus zero switch and motor switches on the schematic, check the wires on the relay coil itself.
- Gently move each wire at the coil lugs and look for broken strands.
Fix
- Cut back to good wire, strip it, and resolder it to the lug.
Unplug the game before working on relay wiring: parts of an EM's wiring carry line voltage.
