AMK compressor fault
Posted: Thu Oct 11, 2018 9:14 pm
Hi,
I have an 07 Disco 3 and it has developed an intermittent fault with the compressor not coming on. It is holding air in the struts ok but on occasion it vents and drops to the bump stops. When it runs again it lifts slowly and the corresponding message shows on the dash. So I know the compressor works and assume that it is raising slowly because the system is empty. On most threads that I have seen the common solution is just to replace the compressor. However I don't want to replace it before I am sure there is not something else causing it to shut down. My Icarsoft shows that the compressor is getting 14v although it is not running until the warning light comes on then the power is cut. I have taken the compressor out and it is relatively clean. The desiccant in the dryer is a whiteish and tan colour and some of the granules have broken down but there is not a lot of power which could clog the system. Not sure if this is an issue. I was checking the continuity in the cables and found that the red and white wires from the plug on the sensor cable to the compressor body have no continuity. Its been a long day but this tells me the wires are broken right? Does anyone know what the red and white wires are for and why they both go from the screw to the compressor body? Perhaps earth wires.
