Looking into purchasing a new Altenator but wanted to get some advice. Looking at Quadratech and they have the mean green. Is it worth dropping 400 on one or can I get away with something a little less expensive? Have some aftermarket stuff but notice the stock one doesn't really cut it anymore.

$400 seems like a lot to drop on an Alternator. How much stuff are you running? I "upgraded" the factory 90 amp Alternator in my YJ to a grand Cherokee one rated at 120 Amps.
-
Not a ton of things. Stereo, aftermarket lights, air compressor..

I would not go that route... no question is a great product, but $400 , no way. The only time you would need that kind of amperage is if you were using an on board welder. Go with a good Heavy duty OM.
Rock Auto has a new 136amp for $166.89.
Then throw the extra money for dual batteries.

Call Tri State Battery in Newark. I've always have good luck with them.

There is a shop on 13 just south of wilm. He rebuilt the pete alt from 100a to a 180a for less then the cost of a new one. Im also sure he puts better parts and pays more attention then the chinese kid putting the average reman together.

And you may need to upgrade your cables if you upgrade to a higher amp alternator.

On my 03 I went with a 136amp alt. from a Dodge Durango and dual batteries.
The charging system is computer controlled so chances are you will never use the Mean Green alt in its entirety.
Toss in a throttle lock and you'll be golden. -
Am I reading this chart correctly? 1 or 1/0 for 136 amp alternator? That doesn't seem right to me. I could be wrong. -

It's based on house wiring where code is involved, the source voltage is 120/240 and the run could be 50' or more.
Try: http://www.bulkwire.com/wireresistance.asp
Enter 6' length, 130 amps, and the default source voltage of 13.85 VDC and 8 gauge copper will cause a .50 VDC voltage drop. More than acceptable in an automotive application.
And even the best alternators will only deliver maximum current at very high engine RPM's.

Toss in a throttle lock and you'll be golden.You can actually fry the PCM/ECU by using a high output alternator.

Thanks for the advice. Not the best with vehicles, but i am going to try and mess around with it this week.

True but going from the stock 117 to 136 isnt that big of a difference.
No problems here on my TJ. The 136amp alt. has been installed for a few years now.
