Okay, heres the scoop. Somewhere between the alternator and the battery, there is a problem,constant battery drain. I have a 4 month old Optima battery, have pulled the alternator and had it tested, everything is fine there. If I start the day with 13 on the volt meter, by the end of the day it is between 10 and 11. Doesnt seem to matter how long the boat is run, whether it is 10 minutes, or an hour straight. Belt is tight as it should be. So, where do I go from here??? -DD Out
