The York compressors mounted on 115 and diesel motors were mounted in rubber. You undoubtably have a bad ground. Run a separate HEAVY ground wire from the compressor body to the intake manifold.

To verify the circuit electrically, an amp meter should show 2-4amps, with less than .1v drop at both the positive and negative connections (the negative connection on a york clutch coil is its mounting bolts). If I am right about the ground problem, there will be significant voltage (voltage drop) between the body of the compressor and any real ground.
