[DK on the road]

        Here is what I thought the battery isolator is. The other picture shows the 10g going into an echo charger. 

Can anyone explain how the echo charger works. It seams to be wired into the house batteries. Although this isn't as important as the charging while going down the road.

As far as loads goes, I don't do anything while driving to add loads. I'm really consistant with what is on and off. I almost always drive with my lights on. I do turn them off when I see the volts low and it may come up .1v, but not much.
