How many volts does a clutch and coil need?

How many volts does a clutch and coil need?

I bench tested the coil with a OHM meter and was around 5 Ohms. 2-5 is a good coil. Hooked up 12 volts to the clutch and coil and the clutch pulled in just fine. Put compressor /clutch assembly back in car and clutch would not engage with the ac switch.

Why does clutch not engage with AC switch?

Put compressor /clutch assembly back in car and clutch would not engage with the ac switch. Checked OHMs on the coil and it was close to .4 OHMs. Bad Coils. Applied 12 volts straight to the clutch coil and still nothing happened other than wires getting hot because of a short.

How do you test a / C clutch coil resistance?

Voltage Test: Remove the plug from the clutch coil and activate the A/C system by placing the selector on cold. Using the 20 volt setting on the DVOM, check for battery voltage at the harness connector. If the battery voltage is present at the plug, test the coil for resistance.

How can I tell if my a / C clutch is working?

You’ll hear a distinctive click when the compressor is energized as the drive plate is pulled into place. The electromagnet does not rotate like the clutch does. It is bolted into place on the front of the compressor. Examine the A/C clutch with a flashlight. In almost every instance when the clutch fails, it becomes burnt and discolored.

What should current draw be at a / C CLUTCH?

Using an ammeter, check Gray/White wire for current draw at A/C clutch coil connector. If current draw is 2.5 4.5 amps, check clutch air gap. Adjust as necessary and retest system. If current draw is not 2.5-4.5 amps, replace A/C clutch coil and retest system

What happens when the AC clutch does not work?

An automobile can have numerous serious problems and a dysfunctional AC compressor clutch is one of them. When this component does not work properly, the engine does not get the cold air flow – leading to some major complications. Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic.
