Im going to hijack this thread as im having the same problem. i have replaced coil, diode, sleeve, and adjusted alignment so the plunger avoids missing the metal cross bar. garage works fine for a few times per game and then slowly starts sagging so as not to allow any balls passage. when i lift up playfield my coil is hot to the touch... My question is, should this coil be getting that hot? ..and any other suggestions.? maybe torturing the metal bracket more so it has even more avoidance away from the metal cross bar?
