The game starts but never feeds a ball to the shooter lane, and the trap door (and sometimes the trunk) never moves. In ball search every other coil fires.
No ball to the shooter lane and trap door or trunk dead: blown solenoid fuse
Cause: One of the solenoid fuses on the power driver board in the backbox has blown, which takes out the group of coils it feeds (the trough eject and trap door among them).
Checks
- Use the fuse chart in the backbox or the manual to find which solenoid fuses feed the dead coils.
- Pull each of those fuses and test it with a meter rather than trusting a look.
Fix
- Replace the blown fuse with the rated slow-blow fuse (3 A slow-blow in one owner's case, for fuse F104).
- If the new fuse blows again, look for a shorted coil, diode or driver transistor before fitting another.
Switch the game off before pulling fuses.
