Stainless steel bracket as earth
Turbo Mini Forums

I made a new bracket to attach my new horn to the front panel using stainless steel. What I didn't think about was that stainless steel isn't as good as a conductor as carbon steel. The horn is single terminal so the bracket is working as an earth. Will stainless steel work as an earth?

Cheers,

Try it and see. I think it will work fine.

Hope so! Couldn't find anything on Google saying it wouldn't work...

Electrical conductivity is pretty much identical to carbon steel (both are crap, you need gold, copper or aluminium for really good electrical conduction, but steel works fine on a car).
All that will happen - over a very long period of time - is corrosion will build up between the two (dis-similar metals plus damp plus electricity = corrosion) which might eventually make the earth bad so make sure the contact areas are as clean as possible when you bolt it up.

Schrödinger's cat - so which one am I ???

It's a horn, not a life support machine...it'll work, dont worry about it.

speed didn't kill me, but taxation probably will

use some electrical conductive grease also known as dielectric grease/paste it will stop any corrosion and help conductivity but like said its just the horn imo

dielectric grease is non conductive.

my bad, it will however keep corrosion away relying on metal to metal contact for the current path

i use copper-ease for this application. seems to work surprisingly well at avoiding dis-similar metal corrosion/electrolysis.
