Credit relay does not pull in. Coin relay pulls in.
When the game is turned on and the score motor and stepper unit are running

I think I have a permanently closed coin switch here is my reasoning:

Coin chute 1 -> adjusted for 1 play -> One coin starts one game. -> if held switch closed manually or shorted it would start games endlessly... which it does.

Coin chute 1 -> adjusted for 2 plays -> One coin starts one game. -> if held switch closed manually or shorted it would add games endlessly to the credit reel ...which it does.

What are your thoughts?

I think that I found it. At some point of doing this the targets started resetting continuously though. I put business cards in both coin and credit relays. The game stopped adding players. I removed the cards until I found the culprit and modified it. It seems like the coin unit advancing issue is resolved. Working on drop targets now.

They just keep resetting. Each time they appear to be reset already.
