Funny I was just on Jegs looking at a 140 amp alternator 1 wire from tuff stuff. What is the benefit of the G3 conversion and what does it entail
This subject comes up quite a bit and has as much controversy as spark plugs or engine oil.
I ran the Powermaster 12SI 100 amp GM 1 wire alternator on a couple of different cars. Part #8002. Fits on the stock bracket with minimal modification. You do have to blip the throttle to make it work. No problems ever.
I only run a voltmeter so the dash light means little to me.
On my Comet I have a Powermaster 1 wire 3G. It's listed in their catalog especially for FE Ford applications. I've never had someone at a car show or the drags tell me I have a Chevy-look'n alternator on my car. Maybe they whisper about it behind my back or maybe they can't tell because I use a low mount alternator bracket.
There are folks who don't like Powermaster products for whatever reason. I personally have never had one of their products fail.
