How can i bypass the computer regulator and install a external? anyone have a diagram? Thanks Wes

 

Older thread, but not answered. The info is on the board, do a search and look in faqs. It is a simple change.

 

 

There are even more compact Nippon Denso voltage regulators that can be had at some rebuild shops. Bolts right onto the alternator with a couple wires hangin off of it. Simple, saw it, never done it however..

 

With my '97 I am going to try to get the old relay type... the buzzer from around 1966. Want to make it emp proof.

 

bringing up an old topic, can this be done with the 24 valves too?? Seems pretty easy if it works

Chris it makes no difference which one, if the regulator is in the pcm the conversion can be made.

 

Thanks Haulin!!
I installed the external VR this afternoon and thank God, I am getting charge now. It is going up and hovering around 14 volt now though. Is this a bit too high??? My alternator is getting quite warm also, but that could be because of the hi draw from the mostly dead batteries

took some temp readings on the alt today. The hottest is got was about 120 deg after running on the road for about 15 minutes. The negine was all the way up to temp so I think this might have been a pretty good reading. My wifes Durango when she pulled in the drive from work was about 145!!

I just went through some charging issues myself. Got it fixed and it nows runs a soild 14V on gauge.(unless grids are cycling)

Here is the internal regulation post.

14 is about right. My big truck charges at 14.5. The stock system is generally a little bit higher than 14. It will work well.

 

i am fighting the same thing except i have no tach ,no charge, and trans will not shift into OD or lock up .

 

Do a search on crank sensor. I think that is where the problem is.
I am not an expert on 12 valve but that is what I have absorbed from the board. There are several experts on here that can help.

 

I second the Crank Sensor. The A/C or cruise won't work either.

 

my A/c and cruise both do not work.....
both otherwise the truck is in perfect working order.(tach is fine, alt is new, lights dont flicker)

could that still be the crank sensor?
It was just off a while ago and gapped properly when re-installed.
no change.
