CIRCUIT DESCRIPTION
The compressor clutch coil is fed power through a control relay and is grounded, based on the A/C enable conditions, through the power module (First design) or directly to generator ground (Second design).

TEST DESCRIPTION
1. This step checks to see if the fault is due to the power module circuit or the compressor circuit.
2. This step checks to see if faulty signal reading is due to the power module or the programmer.
3. This step checks to see if the fault is due to the compressor circuit or the compressor mechanics.
