Electric water pumps (was) alt charging cont sw

[Gary Derian]

Good points on cooling, Greg.  There is no need for an electric power
steering pump, TRW has already designed electric power steering two ways.
One with a motor on the steering shaft and another with a motor and ball
screw directly on the rack.  Peak current draw is high but of short
duration.
