Gottlieb EM Pinball Tip: Inconsistent ‘Add Player Unit’ operation.


Check contacts at Extra Ball Relay, Z1, Z2, 1st Ball Relay, Motor 1A and Add Player Relay… All Good!
Turns out it was the “Hole Switch” Bouncing at the same time as the “Trough Switch” was being activated causing enough voltage drop to fail to trip the Add Player Relay.
