Last night with the batts down to 10.6v I tried passing some volts across the Big Charger fuse (60A 32v Fuse) I push 12.8v in at one end and I get 10.83v out at the other. Problem found and problem solved by installing spare fuse. Question, what can cause this? What could cause the reduction of volts across the fuse?

most likely the fuse was open circuit and the voltage you got at one end was the voltage of the batteries.
