Hey, I am planning to run a high powered audio system (slightly over 1000wrms) in my 1995 YJ 2.5L. I plan to upgrade the stock alternator with a 136amp alt. from an older dodge. I have referenced an older thread on this forum of compatible alternators.
What I am confused about is what I will have to do to prevent any sort of electrical catastrophe. I read this
thread in entirety and I am still confused what I will need to do regarding the factory wiring. I have seen users recommend various things and I am not sure which is the best route.
I was thinking about doing what a user named 'sentinal02' suggested. He has a 1992 YJ and I guess my wiring is the same?
copied from him:
"disconnect the PDC to batt + wire and the alternator end of the two pig tails going to the two fuses in the PDC (the wire that splits). rewire the alt output to go directly to the batt + putting your new high amp fuse in line on this wire. then, connect the alt end of the two pig tails you removed earlier to the batt +.
running the wires in this configuration means you don't have to do anything to the internal terminals of the PDC and it leaves the PDC and the rest of the stock wiring double protected, both by the new high amp fuse which will blow is you exceed the alt's max, and also the two 50 or 60 amp maxi's that it originally had. since we don't know what the current rating for the PDC's bus bars is i found this setup more to my liking. set up like this, i know i can't over load the PDC itself if i tap into the stock wiring where i shouldn't. you'll never be able to draw more than the 100 amps that it was setup to provide originally without blowing those maxi fuses. any auxiliary circuits i can add directly off the batt + terminal with an in-line fuse, or add in a secondary fuse box later on right off the batt."
If someone could explain in simple terms how to do this modification/ rewiring I would greatly appreciate it.
I plan to use all high quality 0-gauge wiring and do the Big Three Upgrade in addition to anything else anyone suggests.
Sorry to post such a convoluted thread, but I wanted to show that I'm trying to make sense of all of this.
Thanks for your help!
