Hello folks,

I was reading the discussion about high powered headlights overheating some
connectors, and again I saw mention that use of dielectric grease is good
practice.  .... to put it on the contacts.  Of course I've seen it
referenced many times.

But this confuses me.  Dielectric grease is an insulator, right?  It is
non-conductive.  Why would we put it on the contacts where we want a better
connection?  Why wouldn't we use conductive grease on contacts?  Or is the
proper application of dielectric grease to put it on the outside of the
connector, but never on the contact points themselves?  I keep a tube of
conductive grease around the garage, use it only very rarely.  If we use
dielectric grease only on the outside of a connection, why not just use heat
shrink tubing?

Thanks!
Roland
