Corrosion on trailer elec. connections.

[showcrop]

Seems like every year it's the same thing. In the spring on a summer trailer or in the fall on a winter trailer, the connections have gotten corroded and it takes awhile to clean them up so that the lights work. Any one got a solution?

If you go to auto supply they have eletrical grease and sprays that will stop corrosion. You can also find it at an eletrical supplier or a hardware store.

Start with new wire. Solder and heatshrink all connections. Use die electric grease on your bulbs and plugs. You will find your lights work pretty much every time.

Plain old Vaseline will work too. It's not as good as the di-electric grease, but it helps a lot.

when not in use I put grease gun grease on my trailer plugs and in the socket on t he trucks.

for the plug ends I just wrap a plastic sandwich baggie around them and rubber band it on to keep dirt out of the grease.

Dielectric grease is what ya need.

any grease is bettern' nuttin though.. keep 02 and water away from the contacts and you are better off..

You have to be careful because some greases will conduct electric which could cause shorting btween posts on plug.

ok.. so don't use one with a metalic content in it... plenty of choices out there.. plain brown chassis grease has worked for me for decades.. cheaper than vasolene or dielectric grease

Well don't use those lights with replaceable bulbs(1157) . Go to the round sealed lights like on semi trailers that will get the light end solved . Then for the lights if you go to Grote or such the whole harness plugs together with few joints or connection issues. For the brakes I prefer air fewer problems.
