yeah,

I was thinking alternator too. However WITH all of this light action going on, the truck still turns over strong.

My headlights are dim, my Radio (pioneer) is showing dc/dc error my battery light is on and my ABS light comes on when I turn on my headlights.

I thought I had it pegged but now I am not sure

 

sounds like alt or battery.. do a load test on both

 

I had my battery light on a couple weeks ago and it turned over strong and ran fine... come to find out my alternator was bad and I was running off the battery the whole time

 

I am going to agree on this one. I see the light flicker out at about 3k on the tach but never stays out.

I see that the voltage regulator is external on the alternator, is there a place I can pick one of those up?
