Arrived onsite for no cooling service call. Customer explained the breaker keeps tripping. Performed diagnostic. Removed compressor from the circuit and fan worked. Tested compressor wires for resistance measure a jumping ohm up to 300. Measures resistance to ground. Took top off and measure resistance on compressor leads. Again had high resistance measurement between leads. Measured resistance to ground in all 3 terminals. The compressor is confirmed grounded. Left plug off compressor. Returned disconnect in off position. Proving for replacement is being worked up.
