Thanks for the suggestions guys. I spent a couple of hours crawling around under the truck last weekend looking at wires and I don’t see any obvious bad wires or connections.
Hatzie, I do own a digital meter that I picked up a while back at Autozone (pic attached). I would be lying if I said I knew how to use it, so thank you for the thorough explanation! Looks like it does have the DCV settings. I just ordered a set of those Pomona leads off of Amazon. I’m determined to figure out the problem because I’m afraid to drive the truck any where now.
