Depthfinder Plugs

[Bluebasser86]

One of my plugs that attach to the back of my depthfinder has some corrosion inside of it and sometimes it keeps my depthfinder from getting power and I have to mess with it for a little bit to get it to work. Any ideas on how to clean it out? It's on the female end of a Lowrance plug. How about prevention so it doesn't happen to my other finder or plugs? Boat is stored outside and it gets extremly humid during the summer and I fish in all conditions if that helps.

Two words. Dielectric grease.

To clean inside the female fitting, I'd get a bit of steel wool, twist it around a toothpick, then spin it around inside the female sockets. Check the male part of the plug. It may be a split type prong. If it is, spread the prongs a tiny bit to make a snug fit with good contact.

Once cleaned, put a bit of dielectric grease on the prong and in the socket connect, and disconnect the plug two or three times to get a good coating on the connectors. You should be good to go with no more problems.

While you're at it, do the same for the bulbs in your running lights as well. Most of the electrical problems occur where components plug together.

You can get the grease at most automotive parts stores. Hardware stores, and Home Depot carry something similar, but it's not called dielectric grease. Stick with the real stuff.
