I'm trying to bring a Nip-It back to life and have hit a road block. The two issues I'm having: zipper flippers immediately reset and the ball count won't advance.
On the zipper flippers once I hit the mushroom bumper the ball index and a - b relay in the body and the 100 point relay in the head activate. As soon as I let go of the the switch the flipper release relay activates and returns the flipper to the open position. The open flippers switch on the playfield is properly adjusted and all the other of pf switches are set to normally open.
For the ball count relay ball one never progresses. I have cleaned the ball count unit and everything appears to move freely by hand.
Any help on where to look would be much appreciated, thanks for looking.
