Ok, so I got a truck that has what I believe to be a short somewhere in the rear lighting system.
Shortly after I bought the truck, it had this very problem, so i rewired the bed (has a flatbed w/ lights in headache rack) and corrected what I believe to have been the cause of why the wires rubbed and shorted.
Fast forward a few years, and the problem seems to have resurfaced, so naturally, I have visibly checked for bare wires and bad connections.. Can't seem to find any.
Why do I believe I have a brake light short? Well, because the "plug" on my brake switch has now melted, and it has popped a fuse. If I stay on the brake long, I can smell the wire getting way too warm. I have a good idea as to which is my problem, however I can not visibly see a problem.. (but it seemed to start shortly after a repair was made, so I'm thinking something in that repair is the problem)
I believe a "amp clamp" would probably help my diagnosing, but I don't have one, nor the money to invest in one this second.. What I do have is time, and a lot of "assorted items" in my shop..
My thought was to use a ammeter to try to "isolate" my problem area.. If I were to add a couple "leads" and probe connections, it should show what part of my circuit is drawing the larger amps, right?? (yes, I have a way of "isolating" all the lights from one another at a junction box like would be used on a semi-trailer)
So, would my thought of using a everyday old ammeter work to show me what light was doing the heavy draw? (I don't see why it wouldn't, so thats why I am asking for opinions.. Hate to spend time trying it to find out it will not help)

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day.
