I had a look at the pic that shows motor up close and the cable going to motor input had black tape wrapped around it and i cant fathom out why. the cables have quite a few swirls and as for putting the cable through the hole in the stub....
a lot of these motors get stuck and the idea is to figure out a workaround all you are missing is ladders to shoot up to motor and reset it but those cables at motor end look a bit of a mess and that one with tape around it I would be curious ie cut it and re do.
are you moving dish to 16e for tonight
are you getting the same installer?
I wonder how good is the viark for use with a motor.
