[QUOTE="Terryl, post: 1065084, member: 369937"] You have the coax from the prime receiver (the vu+ ultimo) going directly to the motor's RX or receiver input right? And if it moves with out the LNB attached then there may be problems with the motor to LNB coax jumper, try a new one. Also make sure that the coax jumper from the motor goes to the #1 port on the LNB. Also how long a run of coax from the receiver to the motor and what type?? Does it have the copper plated steel type center conductor ? A quick test for that would be a small magnet, if it sticks to the center conductor its the CPS type, this type may have too much DC voltage drop on a long run, it may be able to move the motor without anything else attached, but when connecting the LNB and additional switch the voltage drop may be too much and the motor will not turn. And check the DC voltage and current requierment for the octo LNB, the combination of both the motor and LNB/switch may be too much for the receiver to handle, most receivers I know of can only supply 500 mA of DC current, the motor when moving may need up to 400 mA, the LNB and switch may put this over the top, thus the motor when it trys to move will be starving for current, this will cause the system DC voltage to drop, if it drops below the motors lowest voltage specification it wont move.
