dead battery-revisited

Thanks John, your probably right. I'll check. I feel like I'm closing in on a good way to do this...

Thanks, Sebastian

I used the 100 amp cut off swithes to act as a disconnect for both my house and starter batteries to eliminate power loss while in storage. Since these are manual in nature, I would not see why they would not work.

Another option is to get a Relay that can take the load across it in DC but be AC activated so the relay would only be closed if you are on shore power. You would want a manual override or additional cut out relay so that the main relay would not close when the engine is running. I can picture the wiring in my head but putting it in words is hard to do....
