Breaker tripped upon arrival. Checked all high voltage wiring connections before cycling power. Tested resistance to ground on each leg of compressor. Was over 15 ohms on each leg to ground. Internal components are failing. Just a matter of time until unit trips breaker again. System is cooling at this time. Unsure of how long it will last though. Both motor starters are burnt as well. System is at the end of its life. Replacement is recommended. Jacob will come out next week Thursday at 8am for a estimate.
