Hi - I have a BTTF that when I open the coin door and access the switch buttons, I cant get the game to go into the audit or adjustment mode. Normally, having the middle "forward/reverse" switch in the up position would allow me to access the audits/adjustments using the "step" switch. It appears that the game doesn't recognize whether the middle "forward/reverse" switch is in the up or down position. I didn't see any loose wires. Any suggestions? Anyone had this problem with a Data East machine before? Thanks in advance.
