'55 Crown starter cable V8 6v pos ground

[Sarge]

Hi all, new to the forums. Quick question.

My starter has been sluggish for as long as I can remember. I have an aircraft grade cable going to the starter. What I want to know, is does anyone know what the resistance is supposed to be for that wire? Can't seem to find it anywhere, and my old factory manuals are in storage. (I know....) I'm just getting around to tinkering again now that I am out of the military.

Thanks in advance.

Oh, and if anyone would like to link me to any worthy websites that sell parts for my old girl, that would be great.
