Your compressor should have a label showing Running Amps and Locked Rotor Amps/LRA. Our home A/C would show LRA on my clamp meter if the Run Capacitor was bad. With a new capacitor, it started normally and fell into the Running Amps range. If you have a good capacitor and the compressor draws LRA, it's probably shot. We had a case where the compressor wouldn't start. I suggested going to the roof, A/C shroud off, and be ready with a rubber mallet when a helper turned the A/C on. Smack compressor with mallet right when the power came on. This has to be quick, since the compressor has a thermal overload inside and will disconnect the power if it stays at LRA. It worked! I do not know for how long it worked.
