    Default dual battery help

    I think I have everything I need to get going but I just want a second opinion on my layout. Here is how I plan to wire everything, please let me know if I am doing something wrong or if there are any changes I should make before I get to deep into this project. Should I add a switch on the negative side of the relay to control when it links the batteries? The main use of the aux battery is just to run my fridge, I do not have a winch and I have no plans to get one again.

    No, you don't fuse or switch a negative. If you added a switch, it would be on the positive side, never the negative.

    It looks good like it is. Good diagram of a basic split-charge relay. Simple and bulletproof.
