Hmmm- Lets see, when a DC motor stops turning there is no back emf, so the
current is only limited by the circuit resistance (low). The large current
will be flowing through the brushes and armature of the motor. Sooo we get the
convenience of auto up/down at the expense of a burned up motor. Not a good
trade. But wait-- Audi engineers would not design power windows without an end
of travel interrupt switch,would they??. No telling how much trouble Qlisters
will go through for convenince. The race heritage lives on!!
