Greetings. I just picked up a king rock. One flipper is doing a rapid fire thing, I adjusted eos switch but didn't help. It seems there is no power if eos is open at all, I'm assuming coil is bad?

Measure the windings with an ohmmeter. If there’s diodes across the windings, lift one end of the diode. ( I don’t think this machine has diodes across the coils, but just in case….)

I'm not quite sure what you mean from the description. When you say rapidfire, is the flipper machine gunning like an automatic weapon? When you open the end of stroke switch, is there is no movement of the plunger at all?

If above is correct, I would suspect a cracked solder joint or a fractured wire, which usually happens near the solder joint.

When I hold down button, flipper fires like a machine gun. I think it's losing all power once it hits the eos switch and then repowering as it falls back down and the same over and over a gain but very fast. I'll try soldering connections when I go back over tomorrow. Ty for the help everyone.

I would first look for a partially broken wire or a bad solder joint.

From what you are reporting, I would check the wires from the hold coil first. If one of those is not making good electrical contact, then your flippercoil system effectively goes open circuit as soon as the EOS switch opens.

I'll check that out. Ty very much

Look for a broken wire that goes to the center lug.
