I did the clamp meter test, and the amp are fine until the pressure guage goes to 145lbs. then the amp skyrocket and the breaker snaps. I checked all wires , i don't have a capacitor tester, would a bad run capacitor cause this?
My two year old Porter Cable 2 hp motor is having a problem. As the compressor reaches max shutoff pressure of 155 lbs it pop the breaker. I see sparks on end of motor near brushes. It runs fine until it gets close to max pressure. I have new capacitors on it. what causes this breaker to pop? I...
How do i adjust this, it is opening too far? I see pressure close and pressure open screws , but they do nothing. I can't find a manuel anywhere online.
thanks
