Wireing harness corrosion

[PLJ]

We will be setting off tomorrow for a weekend camping at Big Island down by Albert Lea. I just hooked up the TV to the trailer to check all is well. Wouldn't you know it, no lights on the pup, nor is the prodigy glowing green to show me its hooked up. I checked the pins on the TV and I sore some green corrosion on one of the pins. I sanded it off and reconnected and I got a green on the prodigy for a few mins before it died. No sign of life on the lights however. I replaced the wiring harness last year due to corrosion issues. Seems like this will have to become a yearly event. The TV did not come wired for towing when purchased so how many others suffer with this issue for those of us who had after market wiring installed? Did you manage to find a workable solution to reduce the corrosion issue? I'm now off to Uhaul to get another harness

Fill the openings with dielectric grease.  It will stop the corrosion.  Also covering the openings will help too.

In WalMart, they called it bulb grease.

I always recommend that ALL wire splices be soldered and sealed with heat shrink tubing. In your case, I might recommend heating the bare wire with a heat gun before soldering to remove all moisture. Quickly slip the heat shrink over the splice, then heat the heat shrink with the heat gun.

That's the problem with the connectors, no way to fully waterproof them. They sit there 24/7/365 getting salt, dirt, water thrown at them. So that means maintenance. Checking them anually and loading the connector up with dieletric grease will help slow down corrosion problems.

A can of contact cleaner from most any auto parts store or Radio Shack will "repair" all but the worst of corroded connectors.
