i am looking to get a new alternator for my '84 bronco, it has a 351w with a v-belt set up... i have read a few thing on the 3g alts but i was wondering what knowledge the rdc guys have... the alt i have now can't even run the headlights at idle, i think i need more power... what do you guys recommend???

I'm using a one wire from Performance Distributors on my prerunner and have been really happy with it. I also ditched the Ford ignition and use their distributor. They are at www.performancedistributors.com.

I've also replaced the Ford alternator on another truck with the GM two wire from the mid '80's and that's worked pretty well, and is an economical option if you are not running a ton of stuff. I don't have the part number any more but you can find a 95 amp stock distributor with v belts. You have to ream out one mounting hole and make a stand-off bushing out of 1" .250 wall tubing, but if I can do it you can.

Anyway, I have no complaints about Performance Distributors.

Richer auto electric 760-757-1201 New 150 amp 3G alt, bolts right up for about 130$ plus shipping...... I have had Powermasters and other "high output" alternators and they were all junk. They also sell pigtails to hook them up.

P/N's
7752N alt
46-2804 harness
46-2802 other harness

As you can tell, I just went through this........

I figure if the Ford pick-up coil and reluctor are good enough that MSD copied it, that it's good enough for me. I've heard of complaints with the Ford modules, but have never had one fail on any of the vehicles I've converted, even those using all JY parts.
Conversely, the GM modules are power hogs and much more subject to overheating problems. I've debated converting my Sub to some kind of external module just to get it off the engine.

Ollie, if you search 3G's on the FSB bb I'm sure you'll turn up how to convert to one.

Like the last one. I would recomend the 2 groove pulley if you can, it's a little hard on a single belt. We carry spares......

The top bolt hole is small and metric. Drilled and tapped for standard 3/8.

Highly recommend the 3G. One of the most popular conversions with the Bronco/Mustang folks - very reliable unit and an easy swap. You can get them in 95 and 130 amp versions stock.

Ollie, I'm assuming you've read the thread on FSB.com. There's a lot of goof info there.

Have you tested the charging system to make sure it is working properly? Are the headlamps dim because the alternator isn't producing what it's supposed to. Is there another problem (bad ground, corrosion, etc.). I think the 3G swap is a good idea and plan to do it on my Bronco, but I would want to make sure the electrical system is sound before modifying it.

BTW: I work at a large repair shop and we don't replace a lot of 3g alternators.

Ollie, is this what your talking about?

Seems like a good deal to me. I'd buy the harness too. The 160 amp alt is WAAAY more than either of us will ever need, but that's probably what I'll use.

For those of you interested in the swap, there's a lot of good info here:

He's hard to get a hold of at times. But I think if you're ordering something that's not custom and in stock, he'll get it out pretty quick. I ordered a 4G harness from him last year and it came quickly. There have been plenty of guys on the early Bronco lists that have tried to contact him with questions about custom harnesses, etc., or ordered custom stuff and it's taken awhile.

Sorry to hijack the thread but what about Toyota alternators? I dont think my cheap Kragens one is doing the trick I think one of the voltage regulators is shot 'cuz it works here and there. Can I just take off the rebuilt one from Kragens and have a shop rewind it for more amps? I could spend $200+ on a new OEM Toyota one but it will still be stock amp rating. What should I do?

Find a reputable rebuilder and discuss it with them. If you can't find one pm me for a local to me recommendation.

I'm glad I read this thread:D . I went to a local junkyard about four miles from my house and picked up a 3G 130amp alt. for $0 pesos. Yes thats right the guy said "give me a ride in that crazy thing when your done with it and the alternator is free". Of course he also wants a little advice from me when he builds his chevy prerunner. Anyway, I put the alternator in my 71 prerunner F100 and shazam; I have never seen my headlights that bright before:D . Hooked it up with #4 welding cable and the 150amp Mega Fuse from Napa. Also, this conversion eliminated gobs of undeeded wiring harness going to the old alt. and regulator cleaning up the engine compartment. Looks and works bitchen. Thanks for the info guys.
