First of all I just want to say that I do not have a great understanding of wiring electronics so I may ask some very simple questions or some questions that do not even make sense.
So I have two new Garmin Echomap plus 93SV graphs that need to be installed. I also have a Lowrance HDS 9 and a structurescan 3d box currently installed. The HDS/SS3D are both run directly to the cranking battery with the appropriate fuses and such. With these two new graphs (and the livescope box in the future) I do not want to run the wiring in the same way. It would be a mess to have a power cable from the HDS9, the Structurescan 3D box, the console Echomap, the bow Echomap, and the Livescope box all individually routed to the same battery.
Am I on the right path thinking that I can install new switch board on my console that has a single positive and a single negative running to the battery, and from there wire each graph/box to the switch board?
If that's possible I know ill have a lot more questions, like if I can use one switch for the entire electronic system or if I need one switch for each piece of the system, what gauge wire to run from the battery to the switch, if I should just put a new battery on the boat dedicated to electronics or continue using the cranking battery, etc...
I appreciate any input! I plan on taking my time on this and doing it right. I dont mind missing out on some winter walleye fishing if i can be rigged right for prespawn bass.
