[QUOTE="Terryl, post: 1118118, member: 369937"] Disconnect the receiver and do an ohm check of the coax going to the motor, if less then 30 ohms you have a problem in the motor/coax, check the coax for a short, if clear,(infinite ohms <10 meg ohms) then the motor has an internal short and should be replaced. Also check the DC voltage at the receiver, it should be +13 volts to +14 volts DC, or +18 volts to +19 volts DC, (this depends on the transponder polarity) any less then 13 or more then 19 or somewhere in between 14 to 18 volts , then the receivers internal LNB power supply has a problem. Also check the AC voltage ripple, use the AC volt selection on the DVM and see what the AC ripple is on the receivers LNB output, if greater then 100 mV AC then you may have a capacitor problem in the receivers power supply.
