I'm a little new to bass boats so here's my scenario, i've got 3 batteries. Two for trolling and what not, and one cranking battery. What all needs to be hooked up where?! I have a peice of positive and negative wire that I can connect 2 batteries with, guessing that would be the 2 non cranking batteries. I can't tell which wires are for the outboard though and which are for the other stuff. How is your rig setup in this department?

fishinfool,

My outboard is hooked up to my cranking battery.

Everything else is hooked up to my trolling batteries

The cranking battery needs to be hooked up to your motor and electronics, just like your car or truck.  The other two batteries most likely need to be set up for a 24 volt trolling motor.  1 + lead to the trolling motor, 1 - lead to the trolling motor then a connection between the remaining + and -.

Connect the TM cables to the two TM batteries. Connect all other wires to the cranking battery.  If you have two reds and two black TM cables one red and one black go on each TM battery.  Make sure you connect them properly, usually you will get an arc if you try to connect them wrong and can trip the circuit breakers, hopefully you do have circuit breakers on the TM batteries.

The only time I would vary from this is doing a lot of night fishing and using high wattage lights, then I would connect them to the TM batteries.
