jon1998 Posted August 1, 2017 Posted August 1, 2017 Hey everyone, I have another question about the wiring to the ac compressor on my 89 Eliminator. The ground wire on the compressor is cut and I am not sure whwre to ground it. I have heard it is grounded on the back of the compressor itself, but I do not know what exactly to attach it to. I have also looked at a wiring diagram and noticed that this wire is supposed to go to a diode. Do I need a diode? Thanks everybody for being so helpful, this club has been great for learning how to work on my jeep.
HOrnbrod Posted August 1, 2017 Posted August 1, 2017 The diode is a Renix thing to prevent voltage spikes across the compressor coil clutch when energized. You should definitely wire in the diode....
jon1998 Posted August 1, 2017 Author Posted August 1, 2017 Are these diodes vehicle specific? Also, where on the back of the compressor does the ground wire go?
HOrnbrod Posted August 1, 2017 Posted August 1, 2017 They are more A/C compressor specific than vehicle specific. Most all chain auto parts stores carry the diodes. To see where your compressor grounds, download the 88 MJ Electrical Manual HERE
