Engine Size: 1600
Refrigerant Type: 134a
Just wondering why my compressor has 3 pins/wires instead of two? Anyone know what they do? I was just looking to jump my compressor to see if the clutch will engage. No gas in system and the clutch doesn't do anything when I turn the ac on.
Probably two wires for the rpm sensor and one for the clutch coil-- coil has internal ground.
Do not jump compressor with engine running. OK to do it with engine stopped, you should see and hear the clutch plate pull in to the pulley. Running with no refrigerant is bad, that is why it is designed to turn off.
