So, ran across a bizzare thing today. Was reparing up a Tales from the Crypt, and went to test the flippers. They all worked fine. The playfield was up, as I was looking at the coils while they were firing. I put the playfield down, and hit the start button. Game begins...and the upper right flipper doesn't work. Hmm. Raise the playfield. Flippers all work fine. Lower the playfield. Upper flipper stops working. Raise the playfield about an inch with my hand. Flipper starts working again. I've never seen this before. I'm wondering if the coil is somehow grounding on the rails. Will have to investigate more tomorrow, but have any of you guys run across this before?

Ok, you're right, it must be a wire. It switches back and forth between not working, and staying held up now. I've just been over the thing forward and backwards, and I cannot figure out what's causing it. I've run my fingers over all relevant wires at least twice now. How annoying.

Yeah, that was the first thing I did. Of course, there was no continuity since the playfield was up. I went to test it with the playfield down yesterday. The funny thing is, it's stopped now. So I'm just waiting for it to start up again. With a little luck, our guy Carmen will bring his grandson in, and I can get him to play the game all day until it starts acting funny.
