Hello again...still trying to help some local club members with a Coke Vendo drink machine (Model 324185024 971117, Serial # 599847). Original 117v Mag bill acceptor would only take a bill in half way. Replaced with two other 117v units and they did the same thing even though they were properly functioning reconditioned acceptors. Then put in a 24v Ardac with the same result. Also replaced coin mech to see if that was a problem but the result was the same. Does this mean there is a problem with the control board? Any other ideas? Thanks!
