using diodes to step up voltage


Recommended Posts

adjustable would be nice until someone turns it up or something. I prefer it to just be set ~15.3. with my new alt I don't drop at all. :)

lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz.

I cant figure this out on my truck. :( granted my truck is 35 years old. but i am running alts that require one charge wire 1/0, and one wire to the regulator. I would love to charge around 15.0

i made one with a resistor and a potentiometer for about $10. so i can adjust to what ever voltage i want :) 12v to 21v. i have a thread somewhere on here

werent you the guy that wouldnt tell anyone how to wire this up? if not im sorry for the confusion.

I'M NOT SURE, But that sounds similar to my 97 Blazer and 99 Tahoe. The diodes went in the brown wire, its was the only wire that went to the regulator.

I just like to help out. This is something so simple to do but yet companies charge so much for it. I'm not greedy :drink40:

yea im not sure. ive tied it everyway possible, that I could think of. In line with every wire. and nothing. still a grwat thread though. im sure I can figure it out somehow.

I would love to be able to do this on my PT, as MLA wants $249 for a voltage modal for it, $10 would be great! Only problem is, the PCM regulates the voltage in my car, so it probably doesn't work for me :pardon:

Maybe it just won't work on older trucks? I don't know much about alternators, lol.

All this mod does is trick the alt into putting out more voltage. If a MLA works than this should work, you just have to find the right wire.
