i can find the problem !!!
help and thanks friends

 

Make sure regulator has good ground where it is screwed on.
Check the "A" wire. See if same voltage on "A" wire at regulator same as at the battery post.
If voltage same and good ground at regulator then change regulator.

 

subford got it.

Likely bad sense wire.

Replace the pigtail --- almost certain that is likely point of failure.

 

yes a did sr new regulator but do the same thing

 

Correct the problem before driving any further. !8 to 19 volts can fry your computer, blow fuses and burn out bulbs.

 

Check that "A" wire.

firepop5,
I do not think he has a computer.

If you have charge light it should be wired like this.


If you have a gauge it should be wired like this.
