There are charts on the web giving current carrying values for stranded copper wire sizes at various lengths. 6V wire is usually larger than 12V because the amp draw is twice that of 12V. Typically two sizes larger!
Note: when they calculate distance (length) they want you to include the ground return path thru the chassis for a total length number to use in the chart. Just double the wire length for that. Close enough for Gum'nt work.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
