Oh lord please help. I have a cranking and a deep cycle battery. There are wires labeled battery 1 and battery 2. There's a ton of other small wires that go to it as well. My main question is, is battery 1 supposed to be the cranking battery, and if so. How come it has so many extra wires running to it, when battery 2 only seems to have a couple. Any help is appreciated. I'm lost.
