Don't have time tonight to get involved with diagnosing, its probably not a faulty ground, that wouldn't cause the coild and pickup to get hot. Make sure the wires on the pickup are in the right places, I think if your looking at it installed the wire with the boot on it should be on stop. The pickup is made of a coil and transistor, if you put the wires on backwards it will fry the crap out of it.

Coil shouldn't be getting hot like that, it may be bad or something may be wired wrong. There are a couple of wire diagrams on mazdatruckin that might help, I'm still trying to upload more. Look in the B2200 tech section, most of the stuff should be the same or close enough for the B2000.
