Hello, I just received the compressor I bought for my 90 sentra, it is not the same exact model as the one I had. The new one appears to be a NVR 140S while the old one may be a Zexel DKV14 style. The ports and mounting points all measure the exact same as the compressor that I took out of the car so I guess Nissan just used different brand compressors.
The new compressor has 2 wires going into the clutch the old one only appeared to have one, (hard to actually tell as no wires were connected to the old magnet as the magnet sheared off of it's mounting screws).
I transferred the thermal switch over to the new compressor and both wires have plugs on the ends, I just saw a pic of a compressor and it looks like one of the wires coming from the thermal switch is grounded right on the compressor. The new compressor has one wire with a plug coming from the clutch and another wire (also coming from the clutch) with a butt connector on the end of it.
So how do these compressors normally get wired? Does the plug under my hood go to one wire on the thermal switch than the other wire on the thermal switch goes to the clutch?
The coil and the thermal switch need to be in series. I think in that case the wire from the car goes into the coil, then the wire out of the coil goes to the thermal switch, then out of the thermal switch to ground.
ok, so that way if the thermal switch detects the compressor is too hot it breaks the ground causing the clutch to not engage, correct?
ok, thanks. I'm sure my tech will know how it gets wired. I was just wondering.
