My lights just stopped working today on my utility trailer !
I couldn't believe it because I just rewired one year ago and thought I had been real careful with routing and protection and did all the splices with solder and heat shrink wrap.
I can find no physical damage anywhere. I started cutting open the wires on the back lights which were out. By the way, the side markers up front are lit just fine.
So, I have come to learn that the wire I used, from a brand new trailer wiring harness I bought at AutoZone is totally oxidized inside the cable !
The ends are so oxidized they conduct little to no electricity.
So.... I don't want that to happen again.
What wire source do folks recommend for their trailer lights ?
First hand knowledge please. Spec sheets say one thing, experience rules.
