Re: upgrading alternator wiring

To the both of you-

There are two things Jeep is notorious for, overheating, and shit electrical.


I've gone through mine, as have a few others here. Completely gone through my harnesses, replaced wire, increased wire gauge, improved and increased grounds.....etc.....


My shit ain't broke and I dont' talk out my ass. I see nothing but BS out of the two you.










Post up, let us all see your work.


And some numbers.

This is at idle with an operating temp at 208 and a new alternator. Amperage does not change with rpm which means that is all the draw there is.

Voltage drop is a another matter but that's due to undersize wires and not the current demands

Those numbers do not surprise me, about what I expected.

I had read that the average vehicle, factory, requires about 88 amps with AC. Most factory alts produce about 10% more amps than is required.

2.5 Jeeps came factory with a 75 amp alt.



Post #1 of this thread, man is looking at a 160 amp alt, this generally means that one is looking to increase demand.


My SPAL Efan alone requires 25 amps........any of us with extras will be in the 100 amp neighborhood..........light bars, trailer, secondary batteries, amplifiers, multiple fans.....etc....

Nice work.

I am curious why the sideways battery? I have no doubt there is a reason for it.

Re: upgrading alternator wiring

So.... I will start by saying that my dick is bigger and it can handle the load of 160 amps on stock wiring

Having said that - folks... Chill..... As the original poster I will repeat what wss buried someplace in the thread already - it's a jeep but not xj and the 160 alternator is stock. Furthermore I will explain why am I looking to upgrade. The issue came about while towing my trailer and a battery that dropped in charge wouldnt come back up during the 12 your drive. I was able to bring up the battery at home with a big charger.
Granted the alternator might not be able to do what those new fancy chargers do nowadays but I kind of expected for it to at least twitch from the 10.5V a bit.... So my searches yielded what some call big 3 upgrades which mean improving alternator to ground, battery to ground and alternator to battery positive.... And there it seems to be a common practice to run a second wire in parallel..... Anyways.... Never expected that big of a pissing match resulting in I showed you mine... You show me yours (wiring)

Re: upgrading alternator wiring

Are you sure the auxpower to the trailer was working correctly? More often than not I find those don't even work?

Re: upgrading alternator wiring

Yes it was. I tested the output and it was delivering power just fine.

Re: upgrading alternator wiring

Wow ok. That was hard to read through. Anyway I am doing the 160 amp upgrade on my 2000 XJ. The wire upgrade is the only question I have. So I can leave my stock wiring and just add a 4 gage wire from alternator to battery? I know there might be a lot of different ways but this will work right? And if not, does anyone have a picture or diagram of how it needs to be? I can wire up anything, knowing how the wiring is supposed to be, not so great at.

Yes, you can add the wire from the alt to the battery.

Re: upgrading alternator wiring

Most folks run it through a mega fuse first. So alt to fuse - fuse to bat

Re: upgrading alternator wiring

OK thanks Green XJ Jeep and Jeep Driver. The install went great, just a little grinding on the brackets. I will put in a fuse.
