Batery Cable Size

I'm converting from 24 to 12 volt starter on my '79 W900A and replacing the battery cables.

Should I use 1/0 or 2/0 cables from the batteries to the stater?

I'm assuming that 1/0 is ok to set them up in series.

You are right in that the 1/0 is for series compared to the 2/0. I would use the 2/0 to the starter. Don't skimp on this one.

Thank you! I needed some back up on that. The old system only had 1/0to the battery, that just didn't seem right!

A 24 volt system only required the cables to carry 1/2 the amperage load of a 12 volt system so smaller cables work.
