One flipper does nothing.
One flipper dead with fuses good
Cause: A broken brown power wire to the coil (it lands on the outer lug with the banded end of the diode); the wire can break inside its insulation. The under-playfield fuse is after the flippers, so it does not affect them.
Checks
- Measure 43 V at the flipper coil lugs and check the brown wire end to end.
Fix
- Repair or replace the broken wire.
