Has anyone tried an old blue adjustable voltage regulator with a OEM Alty?

[snoopdan 5,000+ posts]

Just curious...I took out my HO Alternators 220 amp that finally bit the big one. Just wondering if anyone has tried hooking up the blue heat sink adjustable voltage regulator for the HO alternators to a stock OEM one. Seems like the wiring matches up, just wondering. I mean, I wouldn't mind a 90 amp alternator that still puts out 14.5 v

That's the one I have. Any thoughts from anyone?

Yeah it will work. Won't give you any more amps, but will work. You could put a smaller pulley on it for like $15 bucks to get allittle more amps.

Why would he be using a voltage regulator to manipulate amps anyway. He knows its not an amp boost.

I believe they all do but since i am not certain i will say that yes, MOST do.

Ok, i'll try it out and report back...probably not this month or the next though. And about 1/2 of alternators are 1 wire, the other are externally regulated via the ECM/ECU

i believe it you need to have an alt that would be externally regulated for it to work right.you may mess up the internal regulater if you use the other.best bet would be to get a vcm from powermaster, talk to scottie johnson

since I never had one how do they wire? Just run the 2 field wires to it? Try out one of these.

STARTERS AND ALTERNATORS

The chrysler guys have been using these for years, on the older cars the reg is mounted on the firewall and on the newer cars its in the pcm, well sometimes the circuit goes bad so they just put an external on their car and wire the field wires thru it.

Scroll about half way down the page to the chrysler/dodge section and there is an adjustable one that goes up to 15.1v

But really I dont see any reason why it shouldnt work a stocker alt, all you are doing is using the field wires to your adjustable reg to control voltage rather than your pcm

Thanks for the link, that provided me with a bit more info. Jeep alternators use the dual field wiring, so i'm pretty sure my big blue will run work with this.
