Can you take some more photos of the face of the coil and the plunger ....out. Got a MM handy? The magnetic comment has me curious. No other issues with the machine? You did say the coil was replaced right? (Sorry if I missed it)

LTG as a JJP tech support you know infinitely more about pinball then I do, but should we not check the resistance (& power coming in) for a bad coil ... like... first...or a close second? I guess if it's stuck coil stop, sleeve, and spacing would be good places to start, but maybe I am missing something. Looking forward to your reply!

In the same boat, but it was a statement. You do know more then me

TB should be able to see this right?

Worth checking, cheep, quick and easy to do.

Nothing in the coil could hold a current with the game turned off so I think your 100% on that. TB check that out and let us know. I am now super curious.

Hang in there, we were all beginners once.

If we think it's 100% mechanical and nothing electrical or otherwise the easy test would be to keep the machine powered off and push up the flipper. If it sticks it's one of the above. If not then report back.
