Ok so ive already posted with a hopper fault. At least it was playin then. Called to local arcade engineer advised me adjust voltage knob. I did and now a code comes up i cant get beyond. Under credits. 618284. Its froze on this. Refill wont get it of. Of and on wont and the reset switch ive since found. Wont leave this screen. Feelin ive wrecked it touching voltage as fruit machine on same extension alarms goin off now if mucking around. If it wasnt for bad luck id have no luck
