Monte, I agree 100%. But did you notice on the Challengers, Chargers, 300's, the batteries are in the trunk and they all have the thinnest ground wire you've ever seen screwed to the frame rail. The Jeep Grand Cherokee has the battery under the passenger seat. I'm pretty sure the ground cable doesn't go all the way up to the engine block either.
The battery is for starting.. all of the sensors
on the car have a common ground so they can talk
to each other.. the alt runs the car and recharges
the battery
