Here is what Tom done to get his machine working.
I got the Bally s5500 working, I had mentioned in one of my posts about two wires coiled up by the power supply. one white with a black tracer and a double black. The wires I think went to one of the validator switches. So for the heck of it I pulled off the connectors on the validator and it now works perfectly. It will pay out when the cash out button is used, no coin drop thru, and I can turn it off and restart and play. Thank you for all the advise and offer to check parts for me. Tom Bera
