Now that I'm going to be spending a lot more time on Lake Michigan, I decided I wanted to run a 2nd battery in my boat. I have a 4.5hp kicker motor, that will be used for trolling, while the main engine is shut down.
I ordered a blue sea battery switch, and 25 feet of 3/0 battery cable. The battery in there right now is a marine battery, but I will be purchasing a marine deep cycle battery to use for the 2nd.
So here is my question. I want all the electronics to run on the deep cycle battery. IE Chartplotter, fish finder/sonar, and troll master. I want the other battery to handle only the main engine starting, and the hydraulic pump.
As of right now, I have one cable that connects to the ground of the engine. The other goes to a 50A circuit breaker. There are two smaller ones that go to the hydraulic pump for the outdrive.
Off of the 50A breaker is a harness and the one red wire coming out of the harness goes to the key switch and powers the accessories when I turn the key switch on. Seems to be a common setup from what I've seen online.
However, this isn't what I need. I want the accessories to be on the deep cycle battery and the rest can stay on the starting battery.
Do I need to cut the wire for the accessory power from the 50amp plug and put an end on it and connect it directly to the new battery?
Or should I leave that alone and run a new wire from the dash were my accessory's all are to the new battery?
