Please help, I’m just about done with a Strike Zone restore. Everything is now working, almost. I’ve repaired the ball count unit, match unit and bell, flippers, and a few other small things. Now when playing there is 1 of 2 things that will happen related to the pop bumpers. When the A,B,C , and D bumper are lit, the gate opens as it should. The problem is that when the ball drains, the bumpers and gate do not reset. Alternately, sometimes when 3 of the pop bumpers are lit, when you hit the target to light the 4th, they all reset and the gate does not open. I’ve trying to find a clue in the manual and schematic but I’m apparently I’m missing something. I’d be very grateful for a little assistance. Thanks.
