Dual Battery Installation
I currently own a 7.3 S2 sloop with a Johnson 9.9 Outboard. There are times I go on an overnite and the single house battery I have will not last two full days. Is there any way that I can use my outboard to charge my single battery? If there isn''t, I would like to hook up a second battery. I have another main switch I can install that has the option for using the #1 battery, the #2 battery or both. My current GUEST battery charger is only a single bank charger. I assume I will need to get a charger that can charge two banks at one time.
1.) Are there any suggestions on how I should wire in the second battery?
2.) How about feedback on the type of charger I should get?
3.) Is there some special hints in hooking up some type of diode to prevent the inadvertant discharge of one of the baterries?
4.) Are there any references I can use to evaluate wiring/hook-up options?
