I wonder if the drill motor is spinning the Chip faster than it wants to , turning it into a generator, and putting 14 or 16V or more onto the motor side of the Chips Victor? maybe that is causeing the Victor to wack out?

Do I understand this correctly - you have a voltmeter on the output side of the Chips Victor, and as you ramp the speed of the transmission up, once it gets to 9V the victor goes dead? what does the meter say then?

is the drill motor still spinning the Chip when this happens?
