Hey, haven't been on here in a while, but i need this forums infinite wisdom again :P

I want to install dual alternators in my truck, im removing the A/C, made a bracket, and will use the stock belt. i can't seem to find any concrete info. i want to have both alternators working together charging the whole system.

I know that i could just go buy a HO alt and call it a day, but i off-road with my truck, and i eat through alts because they just get caked with crud. so i would rather spend less on a 130 amp with a nice warranty. plus the whole cool factor would be nice lol.

the problem i have is how i should wire everything up... this is what it looks like right now.

the truck is a 97 explorer with stock 130 amp alternator, harness has 2 wires (one im assuming is for the volt meter (thin) and other is for the stator/exciter? (thick)

thanks guys

 

nobody?

 

You want it wired in parallel.

 

indeed. same as a battery. in series it would offer 28 volts and in parallel 14 for twice the amps.

at least that's what i'm thinking.

 

so like this would work?

Looks good, but ditch the caps. Also, it doesnt matter what battery the amps wire off of, it might be easier to just use one to distribute power and hide the other one.

 

Looks good. I can't see the use for the caps either (considering the alt and batt you have on-hand) but if you think they look pretty, rock on.

 

for my dual ford 3g's I just wired everything in parallel and it works well...... thats for a 92 ford.... you will want to run the pos from both alts to the same battery though. make sure your wire to the back is sufficiant.... I would recommend no less then 1/0.

 

My problem wouldent be the wiring how do you mechanicaly attatch the alt and find a belt that works and all that jazz..

 

alright, well I guess im going to have to try it now... lol finger crossed.
