The game powers up and starts, the flippers work, but pop bumpers, ball release, drop target reset and every other coil are dead.
Every coil dead but the flippers work: check the 1A under-playfield fuse
Cause: On these Bally-style games the coil power for everything under the playfield except the flippers passes through one fuse under the playfield, near the flippers.
Checks
- Find the under-playfield fuse near the bottom of the playfield and test it.
- If it blows again, check that every coil plunger and mechanism moves freely; members say the centre of the three locks is prone to burning.
- If the fuse is good, check the solenoid supply voltage and the J4 connectors on the MPU and driver board.
Fix
- Replace the fuse with the specified 1A slow-blow, then find whatever blew it before playing.
Turn the game off before pulling fuses. Never fit a bigger fuse than specified.
