I just installed a 16 inch PermaCool fan. I've got the power wired up, and the fan will go when I touch the ground wire to the negative battery lead. But I can't get it to go anywhere else.
How do I ground this fan to a switch? I already have a switch and a 0.00 ohm ground setup, the fan just doesn't seem to recognize it as a ground. If possible, I'd rather not run a wire all the way into and then out of the cab to get back to the negative battery terminal.
