G3 Alternator Upgrade
I got me a 130Amp. G3 alternator Saturday. Pick and Pull price $20.00. You can check it out in my Tech Gallery. Went pretty smooth I should have put my pully on it the one it came with was a little bigger. I'll be finishing up my E-Fan conversion this week and posting pictures in my gallery when finished.

Wow nice work dude. How did you know which alternator was 130amp when you were at the Pick-n-Pull? Did you need to change that mounting bracket or is that the stock one on your truck? How did you make the new 12 and 6 o'clock holes line up? I'm thinking I might want to do this swap too (you inspired me).
Don't forget you need to upgrade your charge cables too. Details on FordFuelInjection.com

Well, I checked the G3s out on FFI and the crossreferenced the Taurus alts. at Autozone and all Taurus 3.8s have 130Amps. My stock bracket already had holes for the 130, I guess because it was an option for my truck. The charge cables already have the two 12ga. fusable links too. I ran it with everything on for about 30 min and the cable to the alt. never got hot.

I need to bump mine up one of these days. The way I'm going to do it is get a reman alternator and the charge cable for it from FFI.
As for not running a heavier charge cable... I guess you could get away without it, but it would safer to run a heavier gauge just for safety (and not to have a fire come out of no-where like the old 2Gs.)

Like I said in an earlier reply my cable and the Taurus cables were the same gauge. The Taurus has a lot more power hungry options than my truck. My owners manual lists two 12ga. fusable links for the 130Amp alt and thats what I have. It's not going to catch fire, it will only melt the fusable links, and it's not going to do it parked it would have to be under full load or dead short.

If you have any high priced electronics... amplifiers, capacitors, wired Sirius or XM radios... don't run the stock cable. If you'd like insurance against an alternator fire underneath your hood, spend the $20 and replace that wire.
I have the 160 amp alternator from www.fordfuelinjection.com... I didn't pay for the charge cable he advertised but I did re-create my own from stereo equipment.
Don't cheese-out on this component. Not worth it.

If I start to have any problems I will definitly go to the larger cable and fuse that FFI suggests, but for now everything is fine. I trust Fords competence on their products, but their Explorers do catch fire.
