Mounting a 136 Amp alternator where the AC compressor used to be on my Renix Jeep XJ.<\/h4>\n\n\n\n

Since I don\u2019t have AC on my off road Jeep, I decided to try to relocate the alternator to the area normally used by the compressor. I looked into making brackets, but I found they were readily available on Ebay.<\/p>\n\n\n\n

When I got the kit, however, I found it will not work with the Renix style compressor bracket. It needs the HO style with the bolts going down into the bracket. Since I had one of those on the parts Jeep, I swapped that out. <\/p>\n\n\n\n

Next I discovered that the bracket will not work with the Renix alternator. The mounting tabs are different. So I used the alternator from the donor Jeep as well. It was a bit stiff to turn at first but it freed up and seemed OK.<\/p>\n\n\n\n

I measured for the belt and found it was between 77 and 78 inches so I got both belts at the parts store. Either seems to work. The 77 inch belt is part number 770K6 and the 78 is 780K6. I did not check to see if they had a 775K6 in stock. https:\/\/amzn.to\/32VhD93<\/a> <\/p>\n\n\n\n

The later alternator uses a different control scheme than the Renix so I had to get an external voltage regulator. I used this one: https:\/\/store.alternatorparts.com\/hd-external-voltage-regulator-conversion-kit.aspx<\/a><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I used a larger black wire for the ground than what was supplied since I already had a wire with a loop end on it on the shelf. I cut the yellow wire on the old alternator plug and connected it to the short red wire on the voltage regulator. I used the supplied loop ends and put them on the red and black wires. I then connected them to the field terminal wires that are held in place by 7mm nuts. I ran the ground from one of the posts on the alternator to one of the mounting screws on the voltage regulator. I connected the oud red output wire to the output post just like the previous set up.<\/p>\n\n\n\n

When I started up the engine, the voltage read 15 volts. This was too high for me. The voltage regulator has an adjustment pot on the back, so I had to unbolt the box from the firewall to adjust it. Note that the unit must be grounded to work. So, I used vise grips to connect the ground wire to the case while I made adjustments. I eventually dialed it in to 13.7 volts. Once it was set, I reattached it to the firewall. <\/p>\n\n\n\n

I ran it for a few minutes and then I noticed that the old alternator from the donor was smoking slightly and making noise. I guess the old bearings were rusted some. Rather than mess with swapping bearings, I decided to upgrade the alternator to the Dodge unit rated at 136 amps.<\/p>\n\n\n\n

I ordered this: https:\/\/amzn.to\/2O2cNCR<\/a>. The case is just slightly bigger and I had to grind on the mounting brackets just a little to get it to fit. I used modeling clay between the alternator and the bracket to see where it was hitting and after a few attempts the larger alternator dropped right in place. <\/p>\n\n\n\n

The wires hooked up exactly the same as the Jeep alternator. Upon starting the Voltage read 13.8V so no adjustments were needed to the Voltage regulator.<\/p>\n\n\n\n

This mod not only gets the alternator up out of the mud but the Dodge unit gives a few more amps as well. I think the original alternator was less than 100 amps so this will be a nice upgrade in winch spinning power.<\/p>\n","protected":false},"excerpt":{"rendered":"
