Spent a good amount of time cleaning up the wire harness. I was fortunate enough to have a wire harness on my 40 that was in pretty good shape to begin with and hadn’t been hacked into and messed with (except for the rear harness, that needed to be completely rebuilt). All areas that had been rubbed through or had exposed wire were repaired and rewrapped with Tess tape and good quality electrical tape. Went through and cleaned/treated every single electrical connection on the harness. First step was to spray with electrical connector cleaner to remove dirt/debris. For really corroded connectors, I soaked in a salt and vinegar solution for a minute or two until most of the corrosion was gone.

Following the salt/vinegar dip it went into a baking soda solution to neutralize the acid. Then a quick dip in 90% alcohol to clean and dry out some of the water. Followed by a thorough spraying of electrical contact cleaner to further dry out the cleaned connectors and wires. After completely dry each connector was sprayed with CorrosionX.

The CorrosionX may be considered on the expensive side, but has pretty fantastic reviews from many in the marine/boating industry. Given my proximity to the ocean (right across the street from my house) I wanted to use a really good product to protect my wiring. Once it is a prayed on, it further attacks any corrosion, even creeping and working it’s way up into the wire under the sheath, and leaves a protective coating to prevent corrosion in the future. I have nothing but positive things to say about it and hope it provides good protection for a long time.

All cleaned up and coated with the protective spray. After testing all of the electrical functions on my 40, I can happily report that they are all functioning normally!

The smile in this picture is genuine, but this photo was taken at the beginning of the wire harness cleanup. I do not think the smile was still there after 4 hours of the tedious cleaning up of the harness. But I’m happy now knowing they are all cleaned up and working properly!
