Well I thought I had a plan until I followed your link Stuart. The
description of the cable says it will not work with gear reduction
starters. I assume that it has to do with the gauge of the wire. I
replaced my alternator wiring with a kit from one of the usual suspects a
while back and I'm wondering if my kit had or should have had the same foot
note.
