Hello, A friend bought me a Sears 919-165220 compressor at a garage sale. It starts, runs for a second or two and blows then trips the circuit breaker in my main power supply box. I opened the air bleader to allow free flow of air, I've looked at the pressure regulator, and the motor wire switch plate terminals, as well as the capacitors to see if I could notice any smells or items not functioning. Everything looks fine. Could I have a bad capacitor? There are two of them. How would I check them? Where would I get a replacement if necessary? Where can I find a manual for this compressor? Thank you for any and all help you can provide.
