How many amps do you have at the compressor since you are measuring current. Using an amp clamp or did you wire your amp meter in line to measure the amount of current the field coil uses? Need more information instead of these one liners. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
