The auxiliary wire from the positive side of my battery to the frame (headlight bucket area) either burned out or just deteriorated due to age and left me stranded for awhile last weekend. I was able to rig something up to at least get me home.
My question is this : what gauge of wire should I use to create a proper one (or two for backup ) ?
I've got some 12 gauge kicking around but wanted to ask the experts first.
Off the battery the big negative wire is going to the engine block and the big positive wire is going to the starter.
Then there is a smaller wire coming off positive to some sort of plastic terminal mounted on the back side of the bumper frame/headlight bucket. I assume this is to power all the smaller electrical components.
This smaller wire is what I'm trying to determine the gauge of. I think the 12 gauge wire I have is too small.
The smaller wire going to the small junction block is actually a fusible link. You'll notice it is likely quite a bit more flexible than standard wire, and the strands are very fine. The coating is kind of brown.
It likely blew for a reason, so don't just replace it with stranded wire.
Did they start the fusible link for that wire in 67? 66 doesn't have that wire to the horn relay protected and that is something I plan to change on my car. It's a bit concerning having a wire that heavy run that distance with no circuit protection.

As I always say when helping people diagnose electrical problems, do you have a service manual? If so, take a look at the underhood schematic, it will show whether that's a fusible link or a wire. I highly suspect fusible link.
