What accessories should be pulling off the cranking battery, and which accessories pulling off the deep cycle?

What is your goal in adding a second battery?What accessories should be pulling of the cranking battery, and which accessories pulling off the deep cycle?
The second battery is strictly for a trolling motor, but the way it is wired with the cranking battery and a 1/2/All battery switch, it appears that everything is pulling off both batteries, and I fear that while fishing, I might pull the cranking battery down as well.What is your goal in adding a second battery?
If the goal is a guaranteed "Start", the starting battery should be stand-alone, with nothing but the engine powered from it
They are only pulling off "both" batteries when the switch is set to both. Otherwise, the load is carried by battery 1 or battery 2 as noted on the switchThe second battery is strictly for a trolling motor, but the way it is wired with the cranking battery and a 1/2/All battery switch, it appears that everything is pulling off both batteries, and I fear that while fishing, I might pull the cranking battery down as well.
My tilt/trim motor and accessories work no matter what the switch is set to. But either way, if I’m trolling, I would need both batteries ’on’ since typically a depth finder, tilt/trim, aerator, and bilge work off the cranking battery tied.They are only pulling off "both" batteries when the switch is set to both.

17’ aluminum bass boat with evinrude 88spl.Starting batteries typically control anything that pertains to the motor, including the trim and tilt. Anything not pertaining to the motor is on the house battery. Trolling motors should have their own dedicated batteries. How big is your boat, motor and trolling motor. The size and draw on each will determine how big or how many batteries you need.
Well, why do 2 battery switches have 2 inputs, but only 1 output? It seems like it defeats the purpose unless you’re solely using it for a double bank. I think what I need to do is have two separate battery switches.Your boat has serious wiring errors.
The purpose of the switch is two fold.....it allows you to charge both batteries with a common source, and it allow you to connect the motor and "accessories" circuit to either battery if necessary.Well, why do 2 battery switches have 2 inputs, but only 1 output?

If you want a particular circuit to draw off a particular Source, the battery needs to be isolated and the circuit wired directly to the Battery.I think what I need to do is have two separate battery switches.
More on this: your entire load of the boat including the trolling motor and starter for the outboard (OB) are all feeding off that one output from the switch and your wiring is probably fine. As mentioned, the selector switch allows you to decide from which battery (1, 2 or both) that the entre load will be connected to. See this link for more explanation on these types of switches.Well, why do 2 battery switches have 2 inputs, but only 1 output?
