I just got a project chicago coin dolphin game. It sat for about 20 years. We got it working great played it but left flipper was weak and out of alinement . we adjusted it and cleaned fingers. It work perfect for aminute then became unresponsive. I lifted playfield and coil was extremely hot. If I manually moved flipper it would move but extremely weakand bearly on its own. Is it the coil gone bad? Is it something else?

If the plunger is sticking in the coil, the coil is shot. And you need to get the EOS points working right so you don't destroy another coil.

the other flipper has no markings. this damaged coil says fl21-375 (williams model) the book calls for a fj29400/21-375. is it the same?

WLL-FL21-375 - Coil FL21-375/28-400 <-Williams coil listing From PBR

It is the same gauge and turns as the Oem ccm. (substitute)

Flipper coils usually have two sets of part numbers (Ex. 21-550/26-1200, EOS flipper wiring) because they have two coil windings on the same solenoid coil body. The first set of part numbers (21-550 in example) indicate the strength of the flipper (pull in coil used to raise the flipper). The last set of (26-1200) indicate the coil strength used to hold the flipper fully upright (solenoid core hold in coil).

The number of wire turns on the second set of the flipper coil part number is always larger then the first number of wire turns because the coil does not need to be strong when holding the flipper upright. The flipper coil "hold" coil does have to be able to be activated permanently without burning up the coil. This is why a lot of turns of wire are used on the "hold upright" coil on a flipper coil. ^ Via Pinball medic^
