REFLECTOR: Liquid electrical tape

[Rene Dugas]

Part of the wiring instructions for my engine EI MVP-50 monitor suggested a drop of 3 in 1 oil on each blade connector during the wiring adventure.  I did it but I am unaware of a problem before.  I have seen slight oxidation at the ground connector in the plane at the panel.  Oil does make it hard to get the connectors apart because they are slippery.  Who'd have guessed?
YMMV.

>> Copper ages very slowly.  If you go to a hardware store and look at copper pipe it will look a shinny red gold.  In my 50 year old house that same pipe is dark brown, almost black.  That pipe has been indoors the whole time.  This doesn't hurt the copper since it's on the surface.  The problem comes in where there is a mechanical connection at a termination.  Surface contamination at the interface can interfere with the electrical conduction causing an increase in resistance and electrical noise.  I forgot to mention CO2 which along with H2O forms carbonic acid which is the stuff that turns copper roofs green.

I have a retract and the exposure to the elements is far greater than a fixed gear.  As to the comment, "Why would you have corrosion?", any thing that is operated outdoors and has electrical connections can and probably will have some degradation of electrical connections over time.  Air contains oxygen H2O and lots of pollution all of which cause corrosion.  Any electrical connection that is in danger of getting wet is at higher risk.
