Last weekend, went to take the boat out (2010 Sundancer 330). Port engine started right up, the Starboard engine wouldn't turn over (sounded like a dead battery). Got it to started a few hours later (not sure why...other then everything turned on for awhile and battery charged?). This weekend, same deal except I couldn't get the starboard engine to turn over at all (dead sounding battery). Got me thinking about the causes (other then the obvious...dead battery). Connected to shore power all week, with battery charger switch on. BTW, emergency start button on helm did nothing. Seems to charge up once all the power on the boat turned on for several hours. Any ideas? Am I doing something wrong when I leave the boat (connected shore power, battery charger on, refridgerators on, both main switches off). New boat for me so I am still learning. Any comments would be appreciated,
