How To Clean A 7 Pin Trailer Connector

• #1

Does anyone have a quick fix to clean the male person and female person ends of a trailer connector that attaches to the back of a truck for the lights, brakes etc.? Somebody said to put brake fluid on them to clean the oxidation from the metal. Does that work? Any other suggestions?

Personally, I use WD40 and fine grit emery textile and that'south only when they really need it.<br /><br />Spray the connector, slip the emery cloth over the end of a flat bladed screwdriver and rub information technology over the metal and you're done.<br /><br />I'd be concerned the brake fluid would break down the prophylactic or plastic body of the connector.

Prevention is ameliorate than cure.<br /><br />Cut the plug and socket off a spare harness and connect the at present blank plug and socket to the truck and the trailer when they are not in use.<br /><br />Adept luck.

WD-40 and a minor round wire brush. Then dialetic grease on the pins.<br /><br />Walmart has plug covers to keep out the dirt & debri.

They're cheap. Dirt/grease is one matter that tin be blown out with just most any solvent in a spray can, but in my opinion they're not worth trying to clean upward if you lot indeed have some corrosion nowadays. The last affair you want when towing in the nighttime is to have merely 80% certainty that you accept a proficient connexion. I'd only purchase a new matched set and replace both ends.

My connector on my truck was corroded real bad. I cut it off and replaced information technology with a new connector. I as well moved it so that instead of existence in the atmospheric condition (under the truck bed) I moved information technology into the truck bed. I have a cover on the bed as well.<br /><br />Terminate result - It's been several years and there is still no corrosion. <br /><br />- Brian

I've seen mechanics at our garage use a wire castor made for male and female ends. Our plugs at work are circular so they won't work for my flat type. I have to believe someone makes a flat version of this but I tin't seem to locate one.

The best way to clean corrosion on electric wires is mix 2 tablespoons of baking soda into eight ounces of h2o. Then either brush on or soak for 2 hours. So clean and shine with steel wool or emery paper. For the female person connector, use a circular wire brush from a .22 burglarize cleaning kit or a .18 air pistol cleaning kit.

If yous desire protection there is a white paste that is available that is a conductor just will not let the metal to oxidize.<br />Under no circumstances put grease or vaseline on any electric connexion.

For the vehicle (female) end of the connector I use toothpaste (extremely mildly abrasive) or Soft Scrub (Comet Cleanser) on a Q-tip in a power drill. Flush with plenty of water and then pack due west/ dielectric grease. For the male portions, Scotchbrite.

Use electrical contact spray bachelor from several manufacturers stocked by all home centers, Home Depot etc in the electric dept. As well, keep from corroding by using electric contact paste for utilize in electrical connections of dis-similar metals. Use the paste to prevent corrosion and maintain good connectivity, and the spray to make clean connections.<br /><br />WD-40 works well merely the stuff that's made for electric connections is the best...
