I was reading yesterday that bad battery connections (dirty) can cause this as well. I literally just replaced one of my batteries and left the other one out. put i tin the water with one and it ran great. Docked it, and put the other battery in... next day it started with the grinding. I know the batteries are good... but the connections I'll take a look at later.

"Hard Spots" in the cable... What you mean by that?
