I have the owner's manual for my 06 32 Sundancer, but it has no info on the two battery switches. And, I'm surprised the manual does not even have an index in the back of the book. So, here are a few of the questions I have that I'm sure you can help me with. 1. I have 4 batteries - one for each engine, one for the gen and I would assume a house battery. Can they all be charged with shore power with both switches in the "off" position? 2. What is the purpose of each switch? It appears one is for the cockpit and the other for the house. 3. With the boat on shore power, is there any reason to turn either/both switch off? In other words, can they be left on all the time when using shore power? 4. What else do I need to know about these two switches that I'm not smart enough to ask?
