Pinball coils (aka solenoids) are windings of insulated copper wire that create electromagnets that make things move on the playfield. If you have a coil that is no longer working, and doesn’t have any obvious signs it has “melted down”, there’s a very good chance you can repair it instead of replacing it. In this video I go over how this is typically done. This works on all types of pinball machines from the EMs to Stern, Bally, Williams, etc.
Repair, don’t replace that broken pinball coil!
