    A/C Clutch Coil

    Inspect/Test/Replace

    • Hook up a 12-volt battery to the clutch coil with an ammeter in series and a voltmeter in parallel.
    • Compare the voltage and amperage to specifications. Generally, if the coil draws more than 3.2 amps at 12 volts, then it needs to be replaced. If it draws 0 amps, check the electrical connnections before replacing it. Always refer to the service manual for the exact specifications for the compressor type and vehicle.
