Another Alternator ? Brand preferences

[Gunter]

i suggest adding a ground for the alternator to the body.
and a resistor for the circuit that tells the alt to charge. i did this for redundancy if the dash bulb fails it still charges. cost is about 5 dollars at radio shack.



:idea:

I'm currently gathering materials to make my own wires. I was going to go with 1/0 or 2/0 welding cable but 5-90 told me that was way overkill and I could get away with less. I still WANT overkill, just not that much I guess.:idea:

Did you immediately notice the extra amperage? Lights brighter, windows faster etc.... or did you needle just not move as far away from the 14 as usual???

No discernible change.

:idea:Where you running the stock wires and battery or had you upgraded those yet? Im just trying to see if it's worth it. I haven't tested anything with a voltmeter but my dash says I start up at 14 and quickly drops to 12is then it plummets when I start turing anything on but never gets down to the red. I'm running an old stock battery, cables and alternator.:idea:

Upgraded wires.
Upgrading the alternator won't change the anemic voltage problems XJ 's have in the cab. I have yet to address that in mine. It involves either replacing the main feed wire with a larger gauge or running a parallel wire of the same gauge along the harness.
I don't know if anyone has done it.. I have done no research on it at all.
