How do I properly install a battery Isolator
How do I properly install a battery Isolator
(OP)
Want to add a deep cycle battery to run my acc. when the vehicle is not running. What would be the proper way to install an isolator so that I'm only using the deep cycle when the key is off or in acc. position?

As I understand it battery isolators are designed to isolate one battery for normal vehicle use and one for ancillary only use for extended use without the engine running and to not drain the starting battery, THEN to recharge each battery at an appropriate rate without the ancillary battery drawing dangerous charge rates from the other battery.
If that is their design purpose, simply wiring them up as normal in the instructions must be all that is required.

Two alternatives are to run dual alternators so that each one independantly charges its own battery and keep both systems totally independant.
I am sure something could be worked out with a few relays and diodes and maybe a voltage controlled switch or maybe even a timer.

It came in handy once when the house batts were to low to start the on board generator. Pushed the button and, voila, power!

You could also get some continous duty solenoids so you can connect the batteries together when you want them in parallel.

The problem is you would not want to remove both batterys from the circuit at the same instant, you would first have both in parallel and then remove one or the other. Or just have the relay to remove the main vehical battery and always have the deep cycle one connected, this maybe the best way to go. Because it makes switching simpler and you get to constantly charge both batterys, when running down the road.

The other one is allowing 2-way power where the auxilaries and main could operate independently or together. This would require some type of high current DC relay, similar to a starter solenoid but rated for continous use.

Automotive charging is voltage controlled, not current controlled. The alternator outputs the maximum charging voltage and any/either battery that is below that voltage will charge until it is up to the charge voltage.
The isolator diodes prevent either battery from feeding the other system. It is two separate battery systems charged (through the isolator)by a single alternator.
A push button controlled solenoid may be added to temporarily connect both systems together should the need arise. The solenoid should be capable of carrying starting current. It may be intermittent rated. It should be push button controlled and used only in case of need. It will defeat the purpose of the isolator to leave the batteries connected with a switch or solenoid.
