Best way to stop electrical corrosion?
« on: May 04, 2019, 04:13:52 PM »
Just did a complete rewire, and read another members post about electrical corrosion of his fuse block   What are the best products that you guys are using to prevent corrosion?  I’m accustomed to just using dialectic grease. Is there anything better out there?

The obvious answer would be to keep the fuse boxes protected from salt spay in an enclosed area. Not so easy though if you live close by saltwater. The spray in the air goes everywhere.

I would do as you do now, dielectric grease or similar product on the fuses when putting them in, and also may be a good idea to take of the cover and lightly spray the whole fuse box with corrosion-X or similar product. If you live close to the ocean, I would do that every month or so.

Dielectric grease is good to put on top of fastened terminals not of fuse blades.
Dielectric grease is not conducive rather a insulator and is used for sealing connections.

I recommend to clean/tighten  your connections, at least twice a year.

You can use products like CorrosionX  or conductive grease.

Just buy the expensive fuses.  :jester: :beerchug:

CRC battery terminal protector is good on the battery. A can would probably last a lifetime.

I use corrosion block.
Works a really well , but is a bit on the expensive side.

I lathered every electrical connection on my boat with Vaseline when I bought it new in 05.To this day I have never had a corrosion issue.I put it everywhere,motors,lights,switches,plugs,fuses literally everywhere electrical.I am the same way with grease,put it on everything.If you get near my boat or trailer you'll get greased but everything works as it should.

Batteries and terminal connections I use Lanocote as recommended by my electronics guy. I use Corrosion X under the cowling of outboards. Dielectric grease works too. Lots of options that work well.

Same here I have Vaseline on everything. I have tubs of Vaseline everywhere. Only  corrosion problem I have had is the pressure switch on my washdown.

Guys be careful with Vaseline on the insulation because its primarily petroleum jelly, it can cause the insulation breakdown and cause premature failure . We have had cases where guy's went buck wild and smeared the whole junction box, connections and insulation only to cause the insulation breakdown and cause a short or fire. FYI Vaseline is flammable

I you want to still use Vaseline before applying test on a small section to see if the plastic insulation on the wire reacts, or just apply a small amount to the blade connections.

I would rather you use dielectric/conductive  grease than Vaseline...

Ok.... so I have dialectic grease, and I also purchased CorrosionX, and corrosion x hD....so which should I use?

So we're saying if I have a Blue Sea 12 position fuse block (or similar unit, weatherdeck etc.) I should remove the cover and spray the interior components with something like CorrosionX?

Where is the fuse panel located? Do you see Corrosion?

Fuse panel at the helm, Safety Hub 150 and weatherdeck in the sponsoons. If I see corrosion is it too late?

I was told this years ago. I was shown  a video on YouTube, I am trying to find it now, that compares vasaline with dielectric grease and tests the destructive properties in vasaline. Long story short vasaline and dielectric grease did not conduct electricity. As far as vasaline breaking down insulation? In the video out of 20 or so tests the tester could not replicate this. I will keep searching for the video. It was very well done.

Dielectric grease does not conduct electricity. It is used to seal out moisture and protect against corrosion. It is also used on spark plug boots to prevent arcing.

Your absolutely right Fisher I forgot the did not. If I remember right the test showed 00 on the multimeter for both.

I have dielectric grease in my toolbox from lubricating the distributor cam on my old 1957 Keith Black Hemi.

I would just use some dielectric on the connections at the safety hub.
