I have a lot of questions about boat electrical systems and was wondering if any of you could guide me to a good online source of info. I was at Boater's World the other day asking questions and the guy “helping” me was full of sh**. I can't stand people who won't just admit that they don't know what the hell they are talking about. I know that this topic is discussed on this board, but I’m hoping to find a more comprehensive online guide instead of searching through 100’s of archived message board threads. Sample of questions I have: How do I calculate when to upgrade alternator? When to use blue tops, when to use red tops? Can I use red with blue? Is there any reason to use red with blue? (one battery for stereo system, one for cranking) Can/should I use my old battery with new battery (not in parallel) What does it mean to be marine rated batteries/alternators? Does it really matter? Thanks
