I've got a Viewsat Ultra and a HH90 Stab motor. I haven't have it up and running for awhile but now find the need to get it going again. My problem is that the Ultra is not moving the dish no matter what mode I'm in. I put a meter on the output to the LBN it reads 13.5 v which I would think is the norm to power the LNB. I don't see any change in voltage when trying to tracking east or west. Does anybody know if I should see an increase in volts when moving the dish? Also any suggestions on how to test the motor?
Thanks for any help.

you will not see an increase in voltage when a move call is sent, 13-18 volts is to control the lnb polarity. So the motor will move at an interanally regulated voltage less then the lowest supply voltage (13v). The motor moves because it receives a positioning signal from the box telling it to use the voltage already there. There is no way of testing the box without an oscilliscope, but most of the time it is not the box. Can you move it from the buttons on the motor? If so, then maybe the box (most likely settings) but if not, then the motor is frozen or not connected correctly. Make sure the motor is the first thing from the box. make sure your coax connections are weather tight. And make sure that your box to motor run is no more than 100 feet with a good quality rg6 or rg6 quad. Hope this gives you some ideas. BG

check if you have reset also and the disque switch can cause some problems also
