I took a Very nice semi restored C 37 in trade... LEDs installed through out.
It came with a few Issues.. These I fixed
Credit Unit would subtract all credits with 1 reset.. Cleaned and lubed unit works fine now.
Ball Count Unit... ball in play lamps flickered or were out. Cleaned and lubed contacts... works fine
Thermometer... not incrementing properly.. once again the shoulder screw in the stepper was gummed up.
Now I have some light and score issues...
The green and purple lamps for the 2 stand ups are out.. so I can't tell if they are scoring 100%
All 10 lamps for 500/5000 & advance are out..
the roll overs do score the points but not the advance. (alternating relay working-changes point scoring)
I do have the schematics and a fluke meter
