Replacing a flipper coil
Steps
- Remove the coil from its brackets and free the plunger; if the old sleeve has melted onto it, keep working it loose, since plungers are harder to find than coils.
- Mount the new coil and fit a new sleeve.
- Move the wires across one at a time from the old coil to the matching lug on the new one; the wires on the centre lug must go to the centre lug.
- On a solid-state coil, check the diode band faces the same way as on the old coil.
- If you lose track, copy the wiring from the other flipper.
