I just had a similar issue on a 2004 LSV. I put a brand new battery in and after 4 days of boating the battery is dead. Thinking of changing the alternator but leaving for the Delta Monday and not sure if I would get one in time. I now have a trickle charger and am thinking of just buying a second battery to have in boat.
Also, is it ok to get a rebuilt alternator or should I get a new one?
Thanks
