altenator power out route?

[elk]

I'm in the process of installing a LiFePo4 battery that will be separate from the starter battery, only connected through the DC/DC charger.
I need to know where the alternator power goes when it exits the alternator. Does it first go to the charger or the 1,2,both,Off switch? I will be putting the Li battery on its own on/off switch to separate it from the starter circuit. So i will lead the alternator output to the DC/DC charger as in the diagram attached.

Please let me know if you have any info that may help me.

Thanks,

Ed
