Hey all. I'm looking for a little advice on wiring of my spare battery and isolator. I realize that the isolator will be added between primary and secondary battery, where my confusion comes in is the placement of my 200 amp circuit breaker, between primary battery and isolator or between isolator and secondary battery or between secondary battery and cap?

Thanks in advance

You should have a circuit breaker at both ends. One next to your primary battery and one next to your backup battery. Then from the circuit breaker to your isolator.
