Okay, I am completely confused on how my dual battery set up works. I just had two amps, new speakers, and a sub installed in my 07 Sunsport. The installer installed a second battery with a switch. The switch has an off, bat 1, dual, and ba2 position.
Now here is my problem.
1. If I leave the switch in ‘dual’ then both batteries our being drained at the same time, and over time, both batteries will drain each other because of the constant charge/discharge state, when the boat is not running.
2. If I leave the switch in ‘bat 1’ then only battery 1 is being charged.
3. If I leave in the switch in ‘bat 2’ then only battery 2 is being charged.
4. You cannot have the switch pass the off position while the boat is running.
In order for me to go from bat 1 to dual (to charge after starting) then the switch has to pass the off position, which is a no no? So how do I run my stereo with the engine off, then when I am ready to start the boat, be able to switch to bat 1 to start then move to dual to get both batteries to charge?
