Following the schematic, here's what I see with this problem:
1) Replay reset relay has a NC switch - that's obviously closed since the coil is energizing.
2) EB play could have a misadjusted switch.
Most likely the culprit is what Minnesota13 said:
The coin switch, located at F-4.5 shows three poles. So, that's probably the problem. Replacing with a new coin switch will probably fix it. Alternatively, if an Xacto can be used to slice and solder to the remaining tab, that should stop Start from energizing. Gotta find the wires, though.
Common is Green with Black tracer
Black with white tracer I believe is NC
and White with a red tracer is NO.
I may have the NO and NC colors reversed.
So, I think
Quoted from bingopodcast:
Stuck coin switch?
Quoted from minnesota13:
I am suspicious of your micro switch wiring. There are three lugs. Your first lug is broken off with evidence of previous soldering activity.
will light the way.
Once that has been replaced/repaired, then we'll have to evaluate. Hopefully Paul sees this and signs on to keep us all updated. You had it cleaned up nicely cosmetically, NoQuarters!
