As I am in a hurry to get the truck in usable condition, I put in another alternator for now. I wired in the brown wire from the regulator, to the D+ on the alternator, and now the light turns on with the ignition key, and goes out when the alternator starts charging.
This is the easy way out, and I am a bit embarrassed, but I can't get a new regulator fast enough to get the original alternator to work.
I though later, why didn't I suggest that you ground the brown wire that goes to the regulator and see if the light works. /even better would be to ground the white wire to the alternator.

If you do get one of the digital ones. Of course I would suggest that you convert to the internal model alternator,SI or CS, for not too much more than the cost of a new regulator.

There are a lot of people who view our posts that benefit from all the information that gets posted. I like to provide as many details as I can.

You should see my pm account.
