my alternator isn't charging. iv done alot of stuff to check it and still cant figure it out. at first i thought it was the alternator itself so i bought one from CL that was new and had my old one checked and the old one was still good. i checked the 120 amp fuse and its still good. i checked the ground for the alternator and hooked it straight to the batt and still nothing.

it stopped charging after i had the head apart and put it back on. i did once arc off the back of the old alternator when re-installing the head but thought it would have blown the fuse. the only other thing that i can think of is the computer since it holds the regulator. is there anyone who has put on a different regulator so you didn't have to replace the computer and is there a way to check if it is the regulator that is causing it not to charge?

 

check the field wires... idk what kinda of voltage would be on the wires, but ones supposed to be a ground the other a hot... the field has to be energized in order for it to charge... no ground, or no power/too little power would mean a no charge situation... you can use and external regulator like the first gens did... it'll just continuously throw a code (or so i've read) i'll poke around... there was a thread about doing this not too long ago

gotcha hooked up bud https://www.dieselbombers.com/12-val...or-wiring.html

 

I say regulator

 

well if its a regulator or to check if it is id like to throw in some sort of external one so if someone knows about how to hook one up id like to hear about it. idc if it throws a code as long as it works.

 

any luck anthony

 

wack it with a hammer repeat if necessary

 

once RSWORDS buzzes by this thread he'll set you up with what you need to hook up the external regulator. it's two wires... ones a constant from the battery i believe and the other is the field wire hook up... which one is which... idk RSWORDS has a nice picture that makes it very clear... seen it b4 cant find it again... sorry, wish i do more to help

 

no luck yet but i sent a PM to RSWORDS so hopefully he will get it soon and ill be able to get it figured out.

 

This is how you hook a ext reg up to a 1st gen. I guess it might work on a 2nd gen.
