I would like to install an isolator for my starting and trolling batteries. My engine is a 40hp 2 stroke cycle Mercury. First, what amp isolator do I need? Second, there are two wires connected to the positive post on the starting battery, is the small one the charge wire or do I need to come straight from the alternator?
