What grease should be used on a starter grounding surface?
I’m slightly confused if it should be something conductive like a copper antiseize or non-conductive like dielectric grease.
I know there are electrical connection greases too so if anyone would recommend those I’m all ears… just have dialectric and antiseize handy.
Thanks!
This may be the ONLY question I'm qualified to answer.
Spent almost 50 years as a master electrician before retiring this year.
There's a compound we've used on conductor connections for decades that resist oxidation and increases conductivity that's called De-Ox.
In truth, the main bonding is through the mounting hardware, so all a compound would really do is help prevent it from rusting.
I've seen some very talented mechanics with the most heinous battery cable connections possible.
Make sure you don't skimp on the conductor sizes to the batteries or the two negative block connections.
I tend to go overboard and make my own 2/0 MTW cable's, with 1/0 grounds.
If you have several strands sticking out of the crimp then you can get a hydraulic wire crimper for about $50 or less, and cut your own ends.
With wire sized big enough to handle the ampacity, good tight crimps and de-ox on the battery terminals I've never had a problem.
You can even recycle old welding leads into custom battery cables.

Made two of the three terminals, lots cheaper, and better.
