Auxiliary Wire from Battery to frame question
Permalink  

Hi guys,

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.

 

Regards, Scott (LandShark ...)

Did you mean Negative side of the Battery. Positive to frame would be direct short to ground.

Does it go to the horn relay ?

Sorry for the confusion.

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.

That makes more sense. As Clint mentioned look into the root cause of the blown link. Then work backwards.

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.

I dug out my Parts Catalogue and Chassis Shop Manual for my 68 Parisienne and they both show a 14 ga brown fusible link wire.

Reading other articles online I see lots of opinions on whether to use another fusible link or an actual fused line to replace it.

Anyone have any experience either way ?

And yes, I will be investigating what caused the recent issue.

I might have a fusible link from a scrapped battery cable, you could use it as a replacement.   However I think it's still sold at parts stores.
