Well, the amp draw doesn't make sense as 14 amps should be doing some work. Did you take the reading on one of the wires going directly into the compressor or the power wire going into the unit?
My guess is your in locked rotor, where the compressor is energized but the motor
won't spin. If you go to a refrigeration
supply house or air conditioning
repair company you can buy a compressor capacitor booster. It just connects up to your existing capacitor and gives the unit a extra boost of power when starting. Full directions are on the package. If you put one on and the compressor still doesn't start, I'd say its shot.
You can test the winding on the compressor if you want by first disconnecting all power to the a/c, remove the three wires that go the the compressor and using your ohm meter to check the windings of the motor
. You should see one letter markings on the compressor R,S,C or Run, Start, and Common. Using your ohm meter, check the resistance between all three and the equasion should work RC + SC = RS
