Your alternator has two 'hot' wires?

>>1127106
Well there is the pre existing wire from the car battery to the alternator. The other wire I have there is to the solenoid, but I could I guess put that to the positive car battery terminal or find a live port in my fuse box. Yes?

This is a joke, right?
Google battery isolater.
Google camping and RV battery setup.

I think either you or I are lost.
Your drawing shows a charging wire from the alternator to the main battery.
It shows a second charging wire from the same alternator going to the solenoid for charging the deep cycle batteries.
What kind of alternator do you have that has two charging wires?

That's what the solenoid and isolator switch are for. You flip the switch and the channel of power is broken

>>1127111
Yes, one wire from the alternator to the car battery. That wire is already in the car. Nothing else in this setup exists yet.

The second wire to the alternator is the primary concern I have here. Should I connect the solenoid directly to the alternator or to the car battery? Or would it work better to go to my fuse box to a fuse that is live when the car is started?

Is this what you're saying?

or does the isolator switch in my diagram need to be only connected to the small terminal on my solenoid and then simply end?

What I'm talking about is pic-related.
You use it to isolate two batteries and you don't need the solinoid.
Plus it correctly regulates charging. There are variants of the pic so get the correct one for your voltage and current needs. They even make one that will allow your storage battery to boost your starter battery. They cheaper ones do not do this but can be jumped with a bypass switch.

What you have there is a potential fire. Also with 6v batteries, the charging rates can be different. Batteries in a series are always problematic.

Not the best read, but it will give you some ideas to ponder.
Good luck anon.
I run a dual setup with Optima Red for the starter and Optima Yellow for my accessories. (winch, stereo, camping stuff)
