Hey all. I've got a dumb question for you. I recently purchased a new to me bass boat (2018 Nitro Z20) with a 36 volt Ultrex. I want to make sure I understand how to use the battery switch before I take it out for the first time. The battery switch in my boat has 4 settings (OFF / 1 / 1&2 / 2). I assume setting 1 is associated with the cranking battery and 2 is associated with the 3 deep cycle batteries. My understanding is that this switch needs to be in the OFF position when plugged in and charging off the water.
When starting the motor, what setting should I be in? When the engine is off and I am running my trolling motor, what setting do I need to be in? In what scenarios should I be in the "1&2" position?
Thanks in advance.
