I'm in the buying stage of the process for the battery to install on the Ramp truck. I want a 12 volt 650 CCA battery min. mounted in the compartment under the bed.
I want to tie to the truck's alternator so I can charge it when I need to.
If I hook this battery straight to the alternator do I need a isolation switch to turn it off and on when using the winch?
I have these already.

Would it be better to hook to the + battery terminal to the winch battery + terminal so I could use either battery if need be?
The ON/OFF switch would be installed on both.
