It's not unusual for the factory to used a large gauge strap like that for the engine block ground.rgk wrote:
I also purchased two 10 gauge wires and four eyelets: one for the negative battery terminal (the wire that extends from the main, really thick negative cable to the body), and one as a replacement for the block to body cable. The current block-to-body cable was incredibly thick, and not so much stranded as much as it was weaved. I've never seen a wire like this on a car before. It wasn't even insulated. I suppose I should assume that it was a last-minute replacement.
It needs to be the same size as the main lead to the starter, so a 10 gauge wire won't cut it.
If you replaced the large strap with a chunnk of something smaller, that may be a problem.
And since it's a ground lead, no insulation is needed. In my climate, those straps can easily last for decades.
Have you had your battery tested? I had a bad connection between a terminal post and the
plate inside the battery once. It was an intermittant problem that was a real bear to find.
