Chassis grounds

[GARY MINKER]

Standard silicon grease is not the best choice for this. In the presence of electricity it can hold moisture and it can promote terminal rot. It is never suggested for use in the presence of RF like coax cables for your CB. Silicon grease needs to be able to breath to stay dry so a sealed environment is not good either. for stand alone terminals, batteries and bolted plates and grounds there is a copper based anti-sieze compound that is loaded with copper flakes and powder suspended in a mineral grease that is absolutely the way to go in humid and splash environments. I have used this stuff for 20 years in 1000 amp systems and ground connections of all types. It can save butt splices from rotting out from dissimilar metals if you dip the ends in it then crimp. Don't use it in multi conductor situations or canon or molex lugs as it conducts from pin to pin. It fights galvanic corrosion and rust while,,, oh yes, it is anti-sieze. Aluminum likes it too.

Although the grease does not conduct electricity, mating the two surfaces with a tight connector will push it out of the way and allow the lug and grounding surface to make a good connection. The grease repels moisture and does a nice job of keeping the ground point clean. Don't use too much, or it becomes a "dust magnet". I've used the stuff to waterproof the ends of battery cable lugs and studs over the years with great results. It does not wash off and can only be removed completely with MEK (Methyl Ethyl Ketone).

Is there anything to paint it with or should you just tighten them after they are cleaned. I want to clean up my grounds this summer. > Don Spithaler > 89 SP 36' > Butler, PA >
