Just starting down the path of my first pinball machine resurrection, a 1965 Gottlieb Dodge City. Item 1 was purchasing the wiring schamtic. I have it, but it's a little daunting. Item 2 was replacing the power cord. I did that, with a new 3 line grounded cord as per the pinwiki instructions.

It's powering on, and playable, but certain things don't work:

1. Score motor will run endlessly sometimes. I have found that the way to correct this is by pulling on the solenoid on the player unit, it sticks and doesn't allow the disc to turn all the way to reset position sometimes.

2. Inability to add additional players. Pressing the Start button makes the player 2 light flash momentarily, but then only player 1 will be playing.

3. Scoring in 5 and 50 increments doesn't work. I can hear additional clicks, but when the clicks are finished, only 1 or 10 points are added.

My research leads me to believe these can all be related to the Player Unit. Am I on the right track here?

It's staying energized for sure.

Thanks for the input everyone. I'm going to venture to clean the Player Unit assembly.

I will follow that circuit and check the trough assembly switch too.

Regarding the Dancer coil, I can't tell from my schematic what activates its on/off position. It looks to me like it's always energized. What am I missing here?

Here you go. I wasn't sure how much of the surrounding area you wanted.

Do switches J, Q, S, U and V energize the Dancer coil? If so I will be so happy and start to think I am getting the hang of reading the schematic

Ah ok, I do see that on the full schematic now. Thank you.
