If on the vehicle you will need a set of gauges hooked up on the low and high sides and if the pressure in the system is equal then the compressor is no good............
If the compressor is off the vehicle the only thing that you can go is rotate the front clutch hub and see if you have both suction on the low side and pressure on the high side, while turning the hub cap off the back ports one at a time.............

How do you test a compressor?
To test a compressor if locked up read the tag on compressor for locked rotor amps, then bypass safety therm-o-switch found under protective black cover on compressor, and with a clamp-on amp meter momentarily run compressor to check amperage.

What is the bar-over test of a compressor?
see API 618 description
What is the bar -over test for compressor?
The bar-over test for a compressor, often referred to as the "bar-over" or "over-bar" test, is a diagnostic method used to evaluate the performance and efficiency of a compressor. This test involves measuring the pressure differential across the compressor to determine its ability to maintain proper pressure levels under load. By analyzing the results, technicians can identify issues such as leaks, wear, or operational inefficiencies that may require attention. Overall, it helps ensure the compressor operates within its optimal performance range.

How do you test a fridge compressor?
If the compressor doesn't start remove all the relays and circuitry installed on it and measure the resistance of the windings A video detailing the process can be found in related links.

Is a megohm test a valid test for checking an air conditioner compressor?
Yes. A megohm test is a way of determining the condition of the compressor's winding insulation. If the insulation is deteriorated or beginning to deteriorate, a megohm test will show this. Generally speaking, 20 megohms or less shows bad motor winding insulation. When AC voltage is applied to a compressor that has bad windings, it will likely blow a fuse as it will short to ground. Moisture in the system can cause a false megohm reading. Also, it is not advisable to test a system that is in a vacuum, as this also can cause a false reading. If a compressor is grounded, a regular multimeter set to ohms will determine this (one probe on any of the compressor terminals and one to the discharge or suction line pipe). A megohm meter will show that a problem is eminent even if the compressor is not yet fully grounded and blowing fuses.
How do you test a Compressor if good on HVAC unit?
With an ohm-meter. Check for continuity in the RUN and START windings, and also from the terminals to compressor case for shorting. There should be continuity in the windings and no continuity from windings to compressor case.
How can you test a air conditioner 3 phase compressor?
just disconnect power & get ur Ohmmeter,and test ; Start-Run//Common-Run//Common-Start..... you should get the same readings on all 3 phases if the compressor is good !!
