I use AutoCAD. Cut my teeth on version 2.17
running in a PC-XT about 35 years ago . . .
so it's kinda in my blood!
There are dozens of cad programs compatible
with the native AutoCAD .dwg file format.
Some are even free. Intellicad is a low
cost program that comes to mind. I've
posted this to the List so that others
with more experience outside the AutoCAD
corral can offer their own suggestions.
You can download any of the z-figures as
.dwg files here:

There are some exemplar wire-books for
complete electrical documentation of
your project here:
https://tinyurl.com/9a5n8jb
These wirebook drawings are divided up
into 'views' each of which is an exemplar
system drawing that prints to an 8-1/2
x 11 inch page. You can pick and choose
from these to use as-is or modify to match
your design . . .will save you a LOT
of work for having created the whole
book from scratch.

Make the aux battery switch two pole
with second pole wired to disable
the starter contactor any time the aux
battery is ON.

There is a very easy to use and free program called Express.sch
https://www.expresspcb.com/download/primary-download-form/
They want your email address prior to downloading the software.
I have a special address for situations like this.

I too used Express.sch over 10 years ago to document everything
electrical. Worked and still works great. Simple, small and easy.
The program is intended for circuit board design so electrical 'logic'
is sort of built in. But the key is that it's simple and easy.
