Hey fellas, what is the correct gauge battery cable I should use for the 12v battery on my '14 Touring? With that in mind, what is the smallest gauge I can get away with?

Hi Bill,

Kind of depends. Do you have a starter on your 14? If not, it really doesn't matter much. There's nothings else that's going to draw amps like a starter does.

"nothings else".... great.

Hey, Jerry

No starter - just my arm! So any gauge will do?

Here's the deal: You probably will be running two headlights, a tail light, and your spark coils, plus maybe a GPS or radio. The total amperage draw would be something on the order of less than 20 amps.

The skinny battery cables used in modern 12 volt cars will handle at least 100 amps for a short burst.

A #12 or #10 wire will handle your load easily.

You could use Romex or other household wire, but be sure to use stranded rather than solid wire. It's more forgiving to vibration.

Hopefully that tells you what you need to know.

P. S. In case you didn't know -- wire size gets bigger as the gauge gets smaller.
