Ok 3G alt has 2 wire total besides the voltage regulator.The stock one has the 3 wires in the 1 plug.While upgrading to the 3G you will need to run a heavy guage wire from the alt to the solenoid or the factory wires will burn up.But is a better system.I've put 2 pictures in this post to kinda show the diffrence.The 3G picture isn't the best but should show the diffrence.

Woah, that alt. doesn't have a fan???

Dbeck002

does it really need one?

It has small fan blades inside the casing.

I just got an alternator off ebay to upgrade to 130 amps. The problem is that the harness for the new alternator is different from the stock setup. Can anyone guide me to any info on the conversion? Or just tell me how to do it. Stock: fan blads on outside, 2 plugs. 130 amp: blades inside, 2 plugs and has ground wire (?). Can I just swap the casings of the two alternators ( put 130 amp windings and rotor into shell of stock and swap regulators)?

First of all, the amps would not hurt anything, that's just how much there is to go around.

Secondly, the one thing that I can already see wrong with that alternator is that it uses the stock charge wire harness. The stock charge wires are something like 10-14 gauge wire. That's no where near what you would need to run 140amps through. It'll run through, but it'll get EXTREMELY hot and probably melt on you. I would go with at least a 6 guage charge wire, and that stock harness plug would not really allow for that. I say if you want to get higher amps without going 3G, buy a 2G unit that was originally made to put that much out, it'll have a new connector for the charge wire where you can use any wire you feel like. I went to NAPA and had them cut me about 9 feet of 6 guage wire. I think you only need 7-8 feet, but get a little more just in case so you'll have room to cut in case you mess up.

BTW, I think NAPA is the only place that would sell 6 gauge wire by the foot, it's kind of hard to find the correct wire, and I think one that is made for it might cost more.

Home Depot also sells all different gauges of wire by the foot in the electrical dept. Just FYI

yea its also the sh-tiest wire in existance. you need high strand, high quality, corrosion resistant, cable. if you get stuff from home depot it will not last a month in the conditions under your hood..

i used 4 AWG high strand audio cable, its good for high temp and the coating isnt PVC. i would use heavy audio wire, its made to handle amps.
