[QUOTE="Analoguesat, post: 949933, member: 176362"] Its possible there were a bad batch of power supplies - Ive seen that on monitor psu's at work in the past. A voltmeter is easy to use - set it to a minimum of 20volts on the scale, and touch the inner & outer of the f-connector port on the back of the receiver. If its on a V polarity channel the meter should read about 13V. If its on a H polarity channel then it should be about 18V. The voltage drop at the far end of the cable between the inner core & the braid should be minimal, if its say 11V & 16V it wont have the oomph to move the dish Clones are normally cheaply built, so its more than possible the power supply is inadequate to move a motor - thats certainly happened with clone 500's in the past - its was reported by more than one member!
