one thing worthy of noting that i was not aware of. carbon fiber is conductive. what does this mean to me? if you have a terminal block with hots screwed to c/f even on rubber mounts...and a terminal block of grounds screwed to c/f even on rubber mounts...they find their way through the screws to each other due to the carbon and tend to make smoke and a nice burning smell. ask me how i know. luckily it was caught quickly and no real damage (just some brownish looking c/f and melted rubber mounts). so what do we learn from this boys and girls? don't screw terminal blocks directly to c/f...bad things happen and always have a fire ext. in your car.

How does this happen? I have terminal blocks screwed down to bare metal in my trunk. The terminal acts as its own isolation. There is 1 large post to act as a common ground for the ground part of the block but other than that is is all plastic and non conductive. The block you are using must be conductive some how?

Whatever, I'm glad you caught it quickly. :)

I hate it when I let the smoke out of the wires.

Good information to know.

What is the electrical resistance of C/F.

ron, these are metal blocks screwed to a metal strap. damn expensive too for what they are, but when you are in a hurry...

genius, not sure on resistance.
