Hello. Started working on a Gottlieb Kings and Queens tonight. Having an issue with the M relay (10 point relay). Start a game and M relay is at rest (as it should be). Once I accumulate 10 points the M relay pulls in and will not release. Another thing that I noticed is that the 10 point reel won't move when points are scored but will reset just fine (so the coil is good on the reel). If the reel scored then that would actuate a switch on the reel that cuts power to M relay. So maybe the reel not scoring is the ultimate issue? What should I be looking at?

You are on the right track alright. A normally closed switch on the 10 reel will open when coil fires to cut out the M relay. Since your 10 reel resets ok then most likely merely a dirty/overgapped/broken switch on M that drives the 10 reel coil or bad solder/broken wire on that switch. M is locking in ok thru both its own lock in switch + that reel switch, so the latter sounds like it is ok.

It's like someone was scribbling letters from an ancient language on it while they were drunk on a roller coaster.

Lol...and thanks it was a switch on M that was dirty/misadjusted. Had same issue with L. It is playing start to finish now (after few other issues were taken care of) so probably clean and rerubber tomorrow then work on getting it 100%. I will report back with any issues. Thanks again!
