Alternator Relocation / Alternator Upgrade

Well I have done tons of research and tons of digging around before i did this. I talked with a bunch of people and took the dive. I completed this about 6 months ago now and it has held up great.

Just for your information I have a 96 Jeep Cherokee Auto 4x4 4.0 H.O.

I first got this information and bought this thanks to dave92cherokee.

When I did it I used autozone p/n 12329, it has the same mounting distance hole to hole as the stock XJ alt's do. When I did it I also relocated it up top to the a/c position. The bracket has to be ground down some due to just the bigger case. Not sure which connection style you have on your 96 as that's the in-between year but it requires the plug in style of the 97+ model XJ's. I just clipped it off in the JY and then soldered it into the wiring harness that's in place. The only reason people swap pulley's is to go from the 7 rib pulley that's on the alt to the 6 rib on the stock xj, but it's not necessary as you can just offset it one rib and it'll run fine.

Now to start this off I removed my battery, battery tray, upper radiator support, fan shroud, alternator, and alternator brackets.

Next is removal of the air conditioner I removed everything the condenser, the lines, the compressor, the hoses, and the drier.

Then I started doing some research and found this.

Now I only used the front bracket I did not use the rear bracket in this mod.

Then you'll notice there is some webbing on the air conditioner bottom bracket, you have to grind most of this away. I found a write up on this a while ago but cant seem to find it again. This part takes a lot of time and patience. Grind and test fit and repeat multiple times.

Once you get it were you need it to be you will get something that looks like this.



I then took the bottom air conditioner bracket off after i had drilled holes through the alternator bracket into the lower air conditioner bracket. Now to get the nuts to fit on the bolts there is some more webbing you have to grind down on the bottom of the air conditioner bracket. In the picture above its were the two lower holes are with no bolts going through them.

Now I had to run back and forth a few times to the auto parts store to find a belt that would fit correctly. I wound up with Masterpro part number K060760 under that it has another number 6k760 the length of it is 76 1/2"

After that everything should bolt up pretty easily and fit like this.



Now you must upgrade the main cables in your jeep with the alternator upgrade. There are plenty of write ups on this I will just post a few pics.

The new cables and materials.


A comparison from the new cable to the existing cables.


This was a lil odd. This is my starter cable.


I had to cut part of it off because part of it still has to be used. This is the part to keep by the way.


Next was finding a hose to work. I used a renix era hose and it works great.


I took a bolt grinded the head down and slid it into the empty slot in the fuse block. Attached my cables so everything is running through that fuse before it gets to the block.

This is the style fuse i used not the exact one.


If you need any more pictures or anything else please let me know I will try to get any that I can to clear it up a bit. Good luck and I hope this helps you out because it took me a lot of work to pull all of this together.

Re: Alternator Relocation / Alternator Upgrade

The ANL fuses are good - they're the same as what I carry.

I could have given you an instruction sheet on what to do at the starter motor - wrote it up a couple of years back, for my own kits.

If you haven't, the use of heat shrink to seal your terminii is strongly recommended! Tape on its own ain't enough - even a single-wall heat-shrink is a major improvement (I use double-wall, lined with heat-activated adhesive. But, I'm cranky - and I buy the stuff in bulk anyhow.)

The fuse block will usually mount on the fenderwell near the battery, and then the lead can be run from it to either the B+ post or the PDC (electrically speaking, they're the same thing.) Problem solved!

Apart from that, it does look like a good mod - can we get you to givvus some more pix of the finished job from various angles? Or, if you like, can you gin something up in MSWord with pix - I can make it into a .pdf for you, and even host it on my site with other writeups (once I get them back up...)

Just wonderin'...

Re: Alternator Relocation / Alternator Upgrade

Glad to hear that alternator is working good for you. I was just getting ready to pick up that very model. Good price for a 160amp and (aside from the grinding) should be plug and play on my '99. Nice work on the relocation too. I'd love to do it, but just can't give up my A/C.

Oh, and definitely ditch the electrical tape and get some heavy duty shrink wrap for your terminals (or is it really terminii 5-90?) as that tape won't hold up well in the long run, especially with the summer months coming up...

Re: Alternator Relocation / Alternator Upgrade

I can absolutely give you more pics of the finished product. I will get the heat shrink on there I was just in a bind trying to get it done, and have yet had the time to get back at it.

Was there anything in particular you would like to see in the pics?

Re: Alternator Relocation / Alternator Upgrade

looks great, thanks for the pics...this just gave me my new project ha.

here's my current routing (minus the mechanical fan and pulley)...i think i can trim that bracket to clear the belt, and just run a much shorter one. im not using my a/c now anyways, its not hooked to anything, it just freely rotates...time to ditch it!

I'd suggest you replace the idler pully for the mechanical fan and revert to that belt routing - if you go to sustained high alternator output, you're awfully likely to start having belt slippage as a result of insufficient wrap (150-180* wrap seems to be about standard for later high-output alternators.)

(By the by - I didn't edit anything in your post, I just hit the wrong button to reply.)

Re: Alternator Relocation / Alternator Upgrade

Haven't had an issue with it, had it that way for about 5 or 6 months...worked fine. If I move the alt up ill have more belt wrap on the pulley than I currently do...so I see no reason not to
