Default corrosion of electrical terminal on battery bank

about two weeks ago my 2007 summit was not responsive when I went to use it. I notice the terminal from the battery charger to the bank was broken from corrosion so I replaced it cart worked fine

Same terminal failed yesterday from corrosion. replaced it cart worked fine.

There is a great deal of green corrosion on the battery terminals which I have not seen before.

What is causing the accelerated corrosion? Weak ground somewhere?

Quite often it's age / condition of the batteries. As the batteries get older & weaker they have to charge harder & longer to reach what the charger considers "full". in the process you have more gassing through the vent caps. The chemicals released are drawn to those electrically charged terminals.

Just about all "melted terminal" issues are because of a bad connection somewhere. I would clean all "large wire" connections on your cart and apply some dielectric grease when reattaching. I bet that takes of your issue.
