Just bought a small Beverage Air cooler with glass door, appears to be an older wine or beer cooler, in a garage sale with lose electrical wires. Appears to be a AZ or BK series.Need schematic to attach wires correctly. HELP!!

Bill, the main reason I've noticed for higher than normal temps in these boxes is filthy condenser coils (this will affect pressures in your sealed system). Remove the front lower panel and inspect your coils. Use a coil brush or a dust broom to thoroughly clean them up, don't use water. You can also pick up some condenser coil cleaner in a spray can from your local appliance parts store, but it's not necessary (the fumes are strong and may be objectionable to your customers... it gets 'em really clean, though!) After cleaning the coils, allow 24 hours for temps to stabilize. If they don't, here is a site for Beverage-Air, contact your local servicer with you exact model and serial number for pressure specifications. http://www.beverage-air.com/technical.service.html Hope this helps! Let us know, will ya?

You would need to be a certified refrigeration technician to even buy R-12, since it is a CRC refrigerant. The kegerator probably doesn't have service ports so you would either have to braze a low-side port in or use a piercing valve, and fix wherever the refrigerant leaked out from. Basically, by the time you pay a refrigeration tech to do all this, it isn't worth it and you would be better off buying a new one

I would definately start there. That is what contols the cycling of the compressor.

Normally thermal overloads have a button like appearance on the compressor. Designed to open circuit when temp has caused distortion to the bi-metal contacts. Upon cooling will close again. Disconnect power before checking continunity on the overload terminals.
