Yep----these days most fiberglass Cobra and other KIT cars with rear mounted batteries are grounded with braided AN hose which they use for double duty of suppling fuel to engine----------

Jerry, I bet there are more out there like that than we can imagine, and that's scary!

i mentioned it to my mechanical genius guru and 1st thing out of his mouth was.
ground the engine to the frame and do the same to the body.
he gave me 2 of those copper braided straps.
ran one from the block to the frame a 12 inch strap.
and one from the body to the frame a 6 inch strap.
i cant believe i forgot the fact that almost every electrical gremlin i have ever chased was a ground problem.
i just figured i'd post this in case somebody gets brain damaged and forgets the importance of a good ground.

Billy,
When I was chasing some problems with my battery size and location I mentioned using one of the copper braided straps for grounding the body reinforcing steel (glass body) to the chassis and was advised not to use them for a primary ground, but to use a regular, insulated battery cable instead. As I recall the comment was that the woven straps absorb moisture and with the electrical flow corrode and fail over time? Seems they were intended to connect body panels, like hood to firewall, but not intended for carrying the full grounding current? Not 100% on that reasoning, but I removed the one I had and replaced it with a short cable. Just mentioning it for consideration, and maybe one of the electrical guru's will comment and correct any mis-conceptions I've posed.
