Can someone explain the On Beam clutch to me?
On mine - go through "A" rollover, the A relay trips and the A pop bumper light relay trips.
Go over A rollover again and the entire cam rotates its full length but A pop bumper trip doesn't reset.
Go through B, C or D rollover, and their two corresponding relays trip, but the entire cam rotates and immediately rests them including A.
I've fixed a few Gottlieb EMs from the 60's but have never seen such an over-complicated relay system.
