What is the air gap set to on the clutch? Did you just run the nut down as far as you could when you installed it or did you set the air gap and stop there? No gap = Clutch is mechanically engaged permanently. The coil being energized or not by the circuit no longer matters because there is no travel for the clutch. Basically, the clutch is defeated so its always on.Air gap must be checked even if you bought a new compressor with complete factory installed clutch because they are often set up wrong. I always check air gap and also bench test the clutch on the compressor to verify its moving in/out properly.
