Cleaning connectors between TV and trailer

You can buy a cleaning kit from tool guys such as Mac, Snap On, etc. Its basically a collection of very tiny brushes and not cheap. You can also use electrical connection cleaner in an aerosol can.

However I find it easier, cheaper and a better fix just to replace the plug if it is corroded. The spring tension on the female part weakens with age and looses its grip - leading to a poor connection.

Regards, Rob
 
I find that a small wire brush (brass--plastic or wooden handle), on the male contacts (there are some where even the male contacts are covered by a rubber shield--often this can be rolled back) to clean off corrosion, and then work the male and female plugs together with "contact cleaner"--it comes in a spray can. I usually then use a grease, or often "Corrosion Block" on the contact afterward. If the female contacts are heavily corroded then I first will use Q tips (I find wooden handled work best. I also have an old larger wire brush, which I can take several bristles and work them around in the female contacts with cleaner.

Something I have thought about, but not used, in a pinch would be pumice citrus hand cleaner, with a Q tip--on the female or with the male pins. You would want to flush with WD 40 or contact cleaner after use and clean with dry Q tips to remove any grit. I find the pumice citrus hand cleaner to be an excellent cleaner for many items, including the "sticky" and dirty residue on fenders or dirty power cords--spray them with 303 for plastic or vinyl after and they will be almost like new.

Rob may have a different set up than our standard 4 or 5 pin--since they don't have any springs in them. The 6 and 7 pin connectors (which I use with the electric over hydraulic brakes) do have a cover with a spring in it. I have had to replace those.

If you hit them with some corrosion block agent after use--you can slow down corrosion..
 
Hi all,
I tow boat, camping, utility, and horse trailers. Here is the one seven pin (I use a conversion plug if I have to connect to a four pin( connector that flat out works. We seem for some reason to have the most problems on horse trailers. This plug uses magnets and not the quick to fail brass springs/pins. I also use contact cleaner every hook up on regular plugs and sometimes a dielectric spray.

I use old chain saw round files and break in half, safe contact cleaner without xylene or other harsh solvents. When done lightly coat with dielectric grease. If you have any male and female or want to buy, use them but I use duct tape
 
I sue caps and plugs on the open connections when not on the trailer, you can also buy a spare 4 wire connector assembly and use the two ends as protective devices (I also use dielectric spay grease but carefully).
