All,
Ive got a renix XJ with the pitiful stock alternator, that is internally regulated. I am looking to upgrade to a big alt for use with LEDs and a winch. Id prefer more current than the 136A ZJ upgrade, since I dont want to do this twice.
My question is, who here has done a renix alt upgrade? I know I could get an ACDelco 334-1446 alt from a durango and get 160A of juice, but id need to figure something out for a regulator, since that alt is externally regulated. I know id also need to grind brackets and get larger cables, thats all good.
I see a lot of threads about later XJ alt upgrades but those dont seem to apply to mine directly, on account of the regulator.
