Believe it or not, while I was leaving this web site I saw some pictures of Ballast resisters. Thinking back to a problem 10 or so years back, another one of the mechs I use changed the ballast. While going to feed the horses I stopped and removed the ballast and found that it was burned in half. As the parts store was closed, I went back to my mech, he was open, dug through old new parts and found a ballast. Put it in and the truck runs great. Tomorrow I'll take for a run, more than backing it out of my garage and pulling back in. $6 bucks on the box (it was very old) and seems as good as new.
So now do I sell it or not. I just started the hunt for a newer truck to pull a travel trailer.
Any takers, can have pics posted Friday as we will be on the road the next two days. 1988 4.0L, 4wd, 5 speed, 44,000 miles original, some rust but not bad as it could be.
