have an 81 ram van b150, we have replaced the alternator and regulator, checked all fuses and fusible links, and the alternator is not charging the battery, just draining it. Can someone please help!!! This is our only family vehicle, and we really need it running!!!!

 

Have you connected a meter to the output of the alternator yet? This can tell you if it's a wiring issue or and alternator/regulator issue.

 

yes we have

 

Then perhaps the replacement alternator or regulator isn't any good.

 

The pcm was bad and instead of paying 250.00 for it a 78 CHEVY alternator fixed the problem...sorry all you dodge guys

 

That is a nice solution. I never thought of putting in an internally regulated alternator if the one internal to the ECM fails.

Is the check engine light illuminated?

Wait a minute, an '81 has an external regulator. I thought the only computerized junk on an '81 was for the lean burn crap.

Color me confused.

 

In his first post he says that he replaced both the alternator and the regulator. So from the sounds of it, he does have an external regulator; meaning that his solution makes no sense. Now I'm confused right along with you.

 

This reminds me of when a Liberal calls into a Conservative radio program feigning conservatism just to get his talking point on the table.

GM guy on a Dodge forum just to bust our *****?

 

First of all I am a woman!! Second got on here looking for help, and no one could tell me what was wrong!! Not trying to hurt feelings but thats what fixed it!!

 

We abuse everyone equally around here.
