Hello all, I have a 1976 Williams Grand Prix pinball that I have pretty much got working. The problem I am having is if I hit the start button everything seems to reset right now. The problem is once the reset is complete and the ball kicks over to shooter lane the motor just keeps running. Everything on the playfield works and you could play the game but the motor keeps running. If i don't put the ball in the game and hit the play button the game will reset and the motor will quit running. But if I put the ball in after that the motor starts running and will not stop until I turn the machine off. When the motor is turning the 5000 for both bonus units left and right are going on and off. The drop targets stay up but its like they are trying to reset. I checked the switches on the drop targets to make sure they are closed when targets are up. I also cleaned them. Anyone know what the problem could be? Thanks
