I am pretty positive it is electrical since we had problems all last summer with the alternator.

But we replaced just about everything related to the alternator(wires, etc) AND the main boat battery, so I haven't been paying attention there.
Thanks again! I'll let you know what happens.
And a battery connection isn't
Make sure the charging lead isn't too short and pulled tight or the nut holding it on isn't loose.
