just got a williams upper deck
when i hit credit button
it never completes reset the score motor conts to turn and the no 4 relay and no 3 relay continue to fire
if i put a few points on the score reels it does reset to zero ok
the players continue too turn in the runner box .
i cleaned and made sure all the switches were making good contact but no luck '
any suggestions
thanks

i don't ,but i could buy one , also 3 wires that went to switches on the score motor were disconnected and wire bugs were placed on the ends of each,looks like this was done sometime ago
when i look at the score motor switch blades i can see 3 tabs that had solder on them but no wires connected at present
the wires sort of point to which tabs they may have gone to .
i will try to take a pic and submit it here, but i wonder since the ends of the wires were protected if this has anything to do with my problem
i will take another look and see what else is happening
could it be a fuse?back lights up .no lights on playfield probably because it is not completing reset ..

Will do thanks
