I want to put together a starter box that contains 2 12 volt batteries for the Sullivan Starter, also I want to use the same box for my 12 volt starter. I'm planning on using 12 and 24 volt outlet receptacles.
Can anyone show me what the electrical schematic would look like?
I'm planning to use 14 gauge wire will this be big enough?

I was also wondering if it would be wise to include a fuse/circuit breaker in the system if so what size should it be?

I did a search but couldn't find anything showing the wiring.

Thanks for any help anyone can provide.

14 gauge wire should be plenty. I don't know about fuse size, but here's a schematic.

Note. You can only have ONE pluged in at a time or voltages will change.

Outstanding !!!! Thanks very much
