So my FJ80 came with dual battery system, isolator and a whole bunch of cut out and buttons to disable / enable the aux battery.
At the moment, the main battery is connected to the alternator charging it when engine is on. Isolator then kicks in when the battery is stuffed and charges the Aux battery.
Now I do need guidance to avoid frying my electrics and better understanding what does what and when, using my amazing drawing skills I have tried to draw the current system which i want to make even more complex by adding a solar panel.
So what I want to know is as follows:

So what I want to know is as follows:
- Does the isolator kick in for charging only ? or does it allow cross battery flow in case one battery is drained?
- Would adding a solar panel with charge controller to Aux battery give me the same result as the main battery with alternator ? i.e at camp would the charge controler charge aux battery then move to main when fully charged?
- If number 2 doesnt work, would fitting the charge controller to the main battery work in principle like alternator ?
