Corroded electrical connectors

I have two 4 pin connectors at foot of mast. Both work intermittently only after twisting. Is theresome way to clean kold terminals or should I just cut them off and wire direct with waterproofing?

Re: Corroded electrical connectors

Not sure how to clean as I do not know what your terminals are made of. I would not wire direct though, you make need to remove the mast at some point. Just smother the connections in dielectric grease to keep the corrosion at bay

Re: Corroded electrical connectors

I'd try to use some sandpaper around the pins to clean the corrosion off of them. Then see if you can find an awl or a needle and see if you can scrape some corrosion off the sockets. Use some wd40 to flush out the socket if needed. Check to see if that solves the problem then use the dielectric and wrap the connection with some rescue tape to try to keep moisture out.

Of course make sure the line is off prior to any of that.

Re: Corroded electrical connectors

You could try soaking the connectors in vinegar for a short while and then cleaning with electrical contact cleaner. They're obviously exposed to the environment so use a slather of lanolin grease pushed into the connectors on reassembly. This will help keep corrosion at bay.

Re: Corroded electrical connectors

There is a tool available that is retractable fiberglass in a pen-shape. It works very well for cleaning stranded wire. I think generically they are just called a Fiberglass Pencil.

Starbrite makes one that is sold at marine stores:
