make sure compressor turns
The purpose of industrial air compressor is to compress air in large amounts and volumes, later storing the compressed air in special tanks or pressure vessels.
the head doesnt effect the output pressure of a compressor package but the size of the piston and the amount of clearence and volume between the piston and head changes your output psi
a single stage compressor only compresses once while a double stage will take the volume from the first stage and compress it more. Makes more pressure but less volume

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.
test
I'm in the process studying for my epa test and this is one of the questions and their answer is foaming occurs in the compressor.
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.
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 !!
Do a compressor oil acid test.
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.
A/C compressor? You need to hook an A/C manifold guage and check low/high side pressures.
With a test light. They lightly pierce the wire & will light up when/if you have current. (Hot wire to compressor for example)
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.
