Isn't the M relay the 100k relay? Does it come on spontaneously or does it stay on once you score 100k?
If it stays on once you score 100k (and fire the 100k relay) it should let go when the End of Stroke switch on the 100k Step Unit is opened by the advance arm. It's a feedback mechanism to make sure the relay sends power long enough for the stepper to complete its stroke.

Quoted from Tonup69:It says: Use - 100,000 Relay
Not very helpful. I think maybe this is one of those small relays in the back box or under the playfield that only has two switches on it
The M relay is the 100k relay. It's mounted in the backbox next to the N/10k relay. The M/100k relay is what sends power to the 100k stepper advance solenoid. If it's stuck on block each of the switches on the schematic closest to the M relay coil with a piece of paper to figure out which one is stuck closed.
