For redundancy sake, i'm going to revisit this topic one more time in all my procrastination.
I am going to get another 12v battery friday. It's not an exact match, but only 2-3 weeks old, and it will be a matching brand from the dealer that installed the original when we bought the TT.
I'll be running parallel.
My switch is 100A continous, and 1000 surge. Other than my breakaway, i want to hook 1 wire from battery to switch, then 3 wires from switch to their destination.
I want to do this on the POS. terminal, for no other reason than because the consensus is 50/50.
I'm good to go, or does someone for see a problem in my logic?
