I searched, but everyone's questions varied a little or were for different applications.

I have the 88 TPI, so my alternator is on the driver's side. I have heard of running bigger + wires to the alternator, and I would like to do this before I put my 140 amp in.

What gauge is good? Is there a part # or will this be custom? Also... what do I do with the + wire on the alternator now?

 

140amp alternator will definetely need a thicker cable, not sure exactly what gauge but there is a formula to figure out what gauge you need for a particulare current. guess im not much help

 

ok i felt bad that i wasnt helping so i found this for you



however, i think thats like the bare minimum before the wire starts to smoke, because it says 10gauge at 150amps 12v, seems too small to me. i think a 4gauge should be fine if you can stand it and find it, 8 should be good too. just be aware you'll have more voltage drop across teh wire the smaller it is.

 

Voltage drop? I don't want that! If I go with 6 gauge I should be ok though, right? I mean, the stock wire is so small!

 

Yea man, six gauge is the way to go if you can fit it; the bigger the better; to a certain point then it's just overkill. But yea six gauge should definitely do you fine unless you feel comfortable running 4 gauge?

 

I dunno, I had 4 gauge for my sound system once, that stuff is hard to work with lol

 

so i to am putting in the 140 amp. run the new wire but leave the old wire on the car not to the altenrator just use it for the fusalbe link on thewire where can you gat fuseable liks?

 

...?
