[QUOTE="A Lancashire Lad, post: 989302, member: 402648"] Have found a circuit diagram which shows the concept. The left side of the is the motor electronics which is still fed from the Tuner LNB supply. The right side shows the relays that switch power to the motor this power would normally come from the LNB feed. This circuit has isolated the relay contacts from the LNB feed, the motor is now driven from an interdependent DC power supply. Using an independent power source could allow you to increase the motor voltage which = increased rotational speed how ever it depends on what voltage the motor has been designed to run on. I cant see how you could inject power into the LNB feed as you still require it to to switch between 13v / 18v.
