outside ac unit is tripping breaker
I have a older central air system the outside unit is a Lennox.
The furnance is in the Basement. The problem I am having is that the outside unit trips the breaker immedetly. Whether i set the thermostat to ac or not. I looked at the wires and don't see any thing wrong. I am completely stumped any help would be appreciated. I will give more any more information as needed and or pictures. Thanks

Turn off power and remove the service panels to access the compressor. Pull off the compressor terminal connection cover and inspect the leads, if they look good go ahead and pull them off taking careful note of which spot they are plugged to. Now simply use your ohm meter to check between each of the compressor terminal posts and then each post to ground, type in your results here for interpretation from the crowd. You may have something else going on but it sure sounds like a dead short in the compressor or fan motor.
