Hello, New here. I have a 1977 Johnson 70 hp and I am trying to determine the AWG size of the existing battery cables. There are no markings on the current cables. Any input would be appreciated.

Interesting read for a guy that is not an electrician. Will be making a copy for my shop wall, thanks ! Just one question, does it make any difference whether a solid wire or multi stranded wire ??
Solid wire should only be used where vibration is not an issue. The current carrying capability is higher for solid wire but not that much more
