Fire Hazard

Beware. I discovered that a splice existed that was not easily visible but could have been a fire hazard. At a minimum it could have burned up, caused fuses to blow and would have been a little difficult to diagnose.

If you replace your Univolt, replace the leads as well. If you still have a univolt, think about inspecting the splices. They are located in an area that may not be as clean and dry as it should be and could cause corrosion...

Here is what I discovered.

Good catch and advice. Sometimes vintage is NOT better.

good catch!

goes with my general theory of wiring: when in doubt, rip it out!

check this thread: http://www.airforums.com/forum...ead.php?t=5264

the problem is not exclusive to the 12v side of things. I nearly burned down my trailer with the 120v system....same corrosion.

I guess I never updated the thread, but wound up replacing the entire box, as the bus-bar in the photo was also corroded beyond repair. and that part wasn't replaceable....so I had to get a whole new box.

anyway, I guess this is just "what happens" to exposed copper over time. condensation, humidity, etc.
