Rear running lights went out
During my last trip I looked at the back of my Tioga 24D while traveling trough AK and the yukon/nwt and saw that none of the running lights were working.
After hunting for blown fuses (none found) I went under the rear of the RV.
There were some black tubes containing wires that go to the various light fictures. And a lot of mud (wet) was also present.
Now chemistry class came to my thoughts and I quickly started to clean the tubes and wires.
Low and behold, my old teacher was right. Due to the requirement of having the lights on while driving, electrolyse started working and the (non -insulated) connection of the (brown) wire was eaten away.
I found all the wires to the various fictures and connected them together again and wrapped the new connection with self vulconizing tape.
(last rol at Radio Shack in Haines).
Now, all my lights are working again.
So, If you clean your camper (RV) also do the rear underside so that no mud stays on the wiring. Check the wires for good watertight insulation.
