Wiring Question

[commanderpete]

I think I need to add a second battery and battery switch. Trying to figure out how to wire it.

The outboard engine has an electric start/regulator, but I mostly pull-start the engine.

Don't really need a "house" battery and "starting" battery. Just want to be able to switch to the other battery if one runs low.

I think the picture below shows how to run the positive cables.

How about the negative cables?

Battery #1 Neg post to Battery #2 Neg post to ???? (Negative Bus???)

Engine Neg cable to Negative Bus?

Trickle charge solar panel wired the same as the engine?

How would you charge both batteries with one solar panel (don't want to combine different vintage batteries)

Not sure if I want to permanently mount a large solar panel and get a charge controller. Do I have a choice? Maybe 2 small panels?.

Would I have to reconfigure everything if I added a charge controller later?

This is the battery I bought 2 years ago. I've treated it well, but it just doesn't have enough capacity.
