Hello, I just purchased a 1971 bally expressway pinball machine. Unfortunately I have no wiring diagrams to work with it. I noticed the 1,000 to 10,000 power up bonus wasn't lighting up so I cleaned the contact wheel and it started working fine.

The next problem I can't figure out is, there is targets you have to hit in order, E X P R E S S W A Y and then you hit the bonus and get points.. i cant get any of the letters to light up. If anyone has electrical diagrams or can help me let me know..

I found one wire in the cabinet that looks like it should be connected to something but is not. don't know where it goes .. i know aprox location but don't want to guess what contact it is suppose to be attached to.



Also what is the best way to clean contacts i've been using metal polish(autosol) and alcohol.
