AC Wiring

Alert me when someone posts in this thread:

The issue started with a broken AC pulley hub. I had been getting AC (even in winter) because the pulley had broken and kept the clutch engaged mechanically. But it finally got very noisy and needed a fix. I got a used compressor from Goldwing in order to get a replacement pulley, and a clutch kit from Adam. Put it all together (onto the original compressor) and the clutch wasn't activating- even with a hot wire to the connector on the side of the radiator.

I took it all apart today and hot wired the coil directly to the battery and bang- it magnetizes as it should, so that part is OK. But if I hot wire the down-side connection next to the radiator where the AC wire comes out of the wiring bundle and check voltage at the connector where the wire goes to the clutch coil (on top of the compressor), I only get a fraction of a volt? I figured I had a problem with the compressor itself, but when I did the same thing to the compressor I got from Goldwing I got the same result- less than a volt going out to the clutch coil if I put 12 volts in?

It seems like that "thing" that fits into the body of the compressor is the only electrical element in the wiring between the two connectors that could be changing the voltage. I was surprised that the voltage dropped the same on both compressors.

Any ideas or suggestions?
