I have just acquired a Bally Nip-it and am going through some troubleshooting. The gator button has been disabled as it broke before I purchased the game. I plan to address that after I get the game otherwise working.

The game is set to free play with an Aligator clip closing the switch that opens when credits run to zero.

The start button does not work or cause any visible or audible reaction when pressed. The switch behind the door does close when the button is pressed and opens when not pressed. The coin mech switches work. The coin switches on the bottom board work. I can play through all 4 players with no problems and it goes to game over.

Help is appreciated.

(Background if it helps.) The game was fully functional and had a weekend of heavy play at TPF. After the move home, the first switch stack on the score motor was deformed and it would not stop turning. I managed to straighten it out and get it to stop in the rest position. I can't say all the switches in the stack are correct now, but the game plays.

The second issue was I could not get the game off of ball one and player 1. I adjusted the switch on the continuous stepper and the coin unit in the head and that got me working enough to play in the current condition.

I do not have a schematic, but one is on order.

Thanks. If there is +50v at the button switch(assuming you mean in the coin door), what part do I check?

Thanks. I will check and get back with results.

Okay I'm a bit embarrassed but really appreciate the help.

The colors are difficult to make out and I can't seem to measure the switches. Not sure what I'm dolooking not wrong with the DMM. I set it to volts and nothing.
I can test the switches and relays. Some work and some don't.
I'm gong to look for a tutorial on measuring the switch voltage.

Testing by hand.

2nd coin chute switch - activates the door coin solenoid and the score motor.
3rd coin chute switch - same as above
Score motor 1 top switch has the black and white. - Same as above
Reset relay - activates above plus the bonus unit stepper
Credit button - no action
Credit unit zero switch - is closed with a clip to set for free play
Coin up limit switch- does not have the wires described (not sure about this one).
The coin stepper sticks a little when counting down credits manually.
Player up unit zero switch - no effect
Ball count unit zero switch - no effect
Game over relay switch - not sure what switch.

Forgive my lack of knowledge here. I'm definitely a visual learner. A video tutorial is my best way of learning. I've been watching Clays videos, but they aren't an exact fit for my game.

If it helps. When getting credits by using the relays under the playfield, it will play an entire 4 player game.

Thanks. The 1st score wheel switch stack was a bit smashed. I flattened it out an the motor seems to work. I'm not sure about the lower switches in the stack.
