The ohm readings across the three windings of a compressor should typically range between 1 to 10 ohms, although this can vary depending on the specific compressor model. The readings should be relatively close to each other, indicating balanced windings. If any winding shows an infinite resistance (open circuit) or significantly different values, it may indicate a problem such as a short or open winding. Always refer to the manufacturer's specifications for the exact acceptable ranges.
What else can I help you with?
On a good compressor using an ohm meter you should get a positive reading from common?
Well, isn't that a happy little question! When testing a compressor with an ohm meter, you should get a positive reading from the common terminal. This indicates that the winding inside the compressor is intact and functioning properly. Just remember to always refer to the manufacturer's guidelines for specific readings and instructions.
When Taking an ohm reading from the compressor terminals to the condensor housing is a way of checking?
Taking an ohm reading from the compressor terminals to the condenser housing is a method to check for electrical shorts or insulation failures. If the reading shows continuity (a low resistance value), it indicates that the compressor windings may be shorted to ground, which could lead to equipment failure. Ideally, there should be infinite resistance, meaning no electrical connection to the housing. This test helps ensure the safety and proper functioning of the compressor in the refrigeration system.
How can amperage in a low voltage circuit be measured?
The question should be, "How should electrical current measured?" Current is measured in Amperes using an Ammeter placed in series with the conductor of the current. This is impractical, so most ammeters have windings of wire that pick up the field generated around the conductor in question. This winding, or coil, is very carefully sized and the meter very carefully calibrated to yield correct readings of current without a direct connection.
How many winding should be there to generate 240 volts on 1500 rpm?
Generator output voltage is determined by the number of windings, strength of magnetic flux and the speed the flux crosses the windings. With the flux and windings remaining the same, a larger unit will have higher voltage than a smaller one. There is no single answer to this question.
What is considered to be the primary side on a step down transformer?
Transformers have windings - typically each winding is designated for a particular voltage. Any one of the windings can be an "output", as any winding can be an "input". Usually for consumers, one of the windings is intended to be 120V for the input. In that case, all of the other windings would be an output.I should also mention that while you can have several outputs, you can only have one input. Some transformers have the windings color coded to designate input and outputs.Hope this helps!
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 do you check mega ohms on compressor?
Usually you check mega-ohms by reading the resistance between compressor shell and the windings. There should be a large amount of resistance which means the windings are not shorted to the compressor case or shell. Use a DVM (digital volt ohm meter) to check the resistance.
My high and low pressure r134 readings are 90-95 each.what should the refrigerant r134a high and low pressure readings be?
If the pressures are always equal running, the compressor is bad and would need replaced
What is a correct resistance reading of the coil for 6.75hp Briggs and stratton engine?
Briggs & Stratton Ignition Coils have NO documented measurement for the primary windings, however readings of between 0.3 and 0.7 ohms are common. The secondary windings should measure between 2K and 4K (including the resistance of the spark lead)
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 !!
Should there be voltage readings across a closed contact?
For all practical purposes NO. The only voltage measured will be the voltage drop of the contact itself. This should be very low if the contact is good.

Where is the air suspension compressor on a 2000 Lincoln continental?
the compressor should be under the hood on the front passenger side, it should be.
Where can I learn about using a cable compressor?
The cable compressor should come with an instruction manual which you should read before operating the cable compressor. There are also some instructional videos on YouTube.
If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?
There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.
