Bill,

I have probably confused the issue, as usual. What I was trying to say was a certain gauge wire will carry a specific amount of current. Think of the garden hose deal again. If you have a 1" garden hose 20 feet long and you splice a 5 foot piece of 1/2 garden hose right smack dab in the middle, you won't get the flow (ampacity) you had with the 1" hose as it now has been choked to 1/2".

The only concern would be with the added length and the reduced gauge. The gauge would only be a concern to the starter proper as it draws a huge amount of current...the charging system and the rest of the truck would be no real consequence.

I'm sure it will be fine, especially if your truck is a 'easy starter' which it sounds like it its.
