Hello EdP. You can test the compressor windings and see if it is good. The run windings will read 1-5 ohms, and the start will read 3-11 ohms. Also check from the terminals to ground and make sure the compressor is not grounding out. If the compressor checks good, then the overload should fix your problem. Hope this helps.
