Just picked up a 1973 Gottlieb Jumping Jack with known issues but I love the pin.
Here’s what it does on startup: GI lights come on along with the tilt light in the backbox. It’s set on free play so when you hit the start button the score motor continually runs and nothing resets including the score reels. The only thing that moves is the score motor.
You can stop the score motor by activating the U relay for the control bank relay reset. The bank resets but nothing else happens. If you manually activate the Ball Count/Player unit and it moves freely and will go to ball 1 player 1 and the flippers activate. Playfield is active but hitting targets or rollovers and no score added and no chimes although the score motor turns once and stops like it should. Score reels don’t move at all and the drop targets do not reset either.
Ball Count/Player unit does not reset by itself.
I cleaned the switches and checked the gaps on the Ball Count/Player unit but that’s it so far. I’ve double checked and reseated all the Jones plugs but still need to clean them up.
Any help is greatly appreciated.
