Gleam, I replaced the corroded, broken clamp used to connect the ground wire to the bus bar. I also removed both bus bars and cleaned all surfaces to insure a good connection.

The end of summer is a good time to pull all the terminals, upgrade the fasteners, etc. Easy summer starting does not require near as much juice from the starting system and any high resistance between the bars and battery lugs can easily go unnoticed. Not only is it harder for the starter to turn the engine over, it may also have to crank for an extended time.

I melted a battery terminal in Yellowstone when the temp was 17 degrees, elevation 8000 feet and the block heater had failed. Detroits don't have the heated screen to warm the air either. I finally got it going with ether and many attempts.

Photos include melted terminal and before and after cable end cleaning.

Pierce, that's what mine looked like. It had worn through previously as I found solder drips on top of the battery...a Mickey Mouse fix.
