So the compressor is tripping the breaker a few seconds after running. I have did all the trouble shooting, Good check valve, Both Caps are good, Motor was checked by AC motor tech and checked out good, good uploader valve is good. Getting 0.118 volts to the motor.
So now Im thinking an electrical problem.
Here's what I have.
Running 220 to the garage, wired to a dedicated circuit in the garage but,this circuit wire is 14-2. I m now thinking I need to change this wire to a 12-2 with a double pole 20amp breaker?
I don't think Im getting enough amps to the motor from the 14-2 wire.

" I m now thinking I need to change this wire to a 12-2 with a double pole 20amp breaker?" That's exactly what I would do. Don't forget you also need to reconfigure the unit for 240. However you could probably get by with just running 12AWG with a 20 Amp single pole.

Sounds like the motor is pulling extra amps to get started and tripping the breaker, or maybe a weak breaker? I would change to #12 wire with a single 20 amp breaker if you are running straight 110.
