Had my alternator and battery tested and they both are good. I suspect the voltage regulator is going bad. Any thoughts would greatly help.

 

Geez it's been this long and nothing.. Thanks for the help guys..

 

It's been two hours you impatient jerk.

 

That ^

 

Well it's kind if important and I thought I'd get plenty of help here

 

You would, if you aren't impatient.

The voltage regulator is inside the alternator, if the alternator tests good then the regulator is good too.

 

Are you positive on that? Just need to be sure cuz I have a job and ****

 

With everything off and doors closed use a multi meter to see how much of a draw is on the battery. Then get in the truck, close the doors and pull out each fuse for a second and have someone watch the meter. This can be the easiest way to at least track down the circuit its on.

 

What does having "a job and ****" have to do with what Sean told you? You came for help and he gave an answer. If the alternator tests good and it has an internal regulator then that tested good too.

Does it drain while off? Does it not charge properly while running? Have you done any other trouble shooting? Pulled codes? Where were those parts tested?
