New to this site and power boating. Just bought a 2006 sundancer 300 and I think I mucked up my batteries some how. Boat was running fine and then we hooked up to shore power overnight and didn’t switch the shore power switch to on and never turned on the AC convertor switch to charge the batteries. The next morning there was a weird alarm sound in cabin and my port engine would not start. We plugged into shore power again and made sure all switches were turned on to charge battery. It looked as though the battery charged (although not fully) and I felt confident that my port engine should start. That was not the case. I was able to eventually get the port engine to start - only because the throttle had to be jiggled to make sure it was truly in neutral. The throttle is a separate issue and probably needs to be replaced. After taking boat out to mooring and trying to start a cpl of days later, nothing. No power whatsoever. Generator will not fire up and the AC volt meter shows a weak battery. Any thoughts on what is going on? Going to have a mechanic take a look but if it’s batteries at end of life, I figured trying yo replace them myself.
