So your saying cranking my car for say 30 seconds is
the same as grounding my positive lead for 30 seconds?
 Hmm, last time I cranked my engine for that long the
main power feed didn't start on fire.  Unlike last
time I shorted my unfused amp wire in my old Jeep when
I stepped on the threshhold to get something off the
roof.  Luckily I had a shovel to pry the wire off the
battery.  Trust me, you need a fuse there.

Yea, that usually a good thing.
