How to get a good ground in your Mopar

Get one of these piloted brushes. They do an incredible job of removing all paint, corrosion, etc. and look much more professional than using a piece of sandpaper. Attach the terminal and cover the connection with something like LPS3. You won't have any problem with the connection.

Very cool. Where do you get those?

Also don't forget the star washer between the terminal and the metal surface. The purpose of these is to bite into both surfaces to enhance the ground. They should not be installed with the intent of locking the screw head to the terminal.

Tell ya what. In about a six months I'll probably be ready to trunk mount the battery in the 67. I still have a couple of great big carbon piles, and between the two of 'em I can put about 1000 amps of load on the system. Remind me along about September, and I'll do some serious testing.

That ought to do it. With that kind of load, I'm pretty sure you'd be able to measure a voltage drop even across the cables. I'd guess you may likely see the most significant drop across the connections to the sheetmetal, but I'm sure if you must, and you are willing to maintain the connections, that such a setup will be servicable. My experience is that, much like Ohm's law, Murphy's law hasn't changed much over the years and the likelihood of a failure increases as your turn at the starting line comes up. Never say never.

I keep getting down to your signature line and I completely forget what was said!

Too much action going on for me to concentrate!
