The DC current draw would be about the same, the higher DC voltage would cause the motor to move faster, now if the motor is getting old or has a binding problem, it's initial starting current would go up,(for a very short time) this could cause a blown switch if in-line before the motor.Try this (when you get the chance), move the motorized dish to a satellite, check for a good signal, then shut things down and by-pass the motor, see if your switching problems go away or still remain the same, if still the same you need a new switch.</blockquote>
