When I push the left button ...

Lock Relay pulls in
Tilt Relay pulls in

When the coin switch is activated ...

Replay Relay pulls in
Coin Relay pulls in
Tilt Relay is reset if the score motor runs

I have messed with for a couple of days and can not get the game to start.

connections look good and I have tested with a multimeter
I have looked at all the switches and they look OK. Have only cleaned a couple.

Any suggestions or help would be appreciated. I have read what I could find on the internet.

Made some progress. I can now get the game to start-up, but I have to manually actuate the score reset relay until the score is all zero. The hot wire from the score motor to the score reset relay has continuity. Switch is making and breaking on the score motor.

It does have a Reset-Relay and it works just as you described. It was not pulling in when I started working on it this morning, but it now does. As long as it is pulled in, the start-up motor runs. ... unless you set the score to all zeros. I do that by pressing the score reset relay several times until all are zero.

I have not tried cleaning each jones connector, but I did go down each one with a multi-meter. I assume that is not a 100% way of checking as you can get continuity through other wiring.

While the reset relay is pulled in, the score motor is running, but the score reset relay does not cycle and reset the score.

I tried pressing the armature of the Reset Relay the same time as the Coin Relay is pulled in. Same result. Score motor runs, but the score does not attempt to zero.

Cleaned the Jones connectors. Same result. Score will not reset.

Fixed it. Bad contact on the coil relay. Adjusted.

Thanks for all your help. Got it working.

I am not sure if the special is working correctly. If you knock down the targets with special on, the solenoid on the credit unit pulls in, but does not release until you roll over the target reset button. Seems like a good way to burn up a solenoid.

I can scan in the wiring diagram if you still want. May be a few days.
