You can check this out for yourself by following the section titled,
"CHECKING THE ROTATOR FROM THE GROUND" in the manual which you can download
here: http://www.hy-gain.com/man/pdf/T-2X.pdf
<http://www.hy-gain.com/man/pdf/T-2X.pdf>A slow motor is usually some
resistance causing something to heat instead of using the energy to turn the
motor, so you should be able to detect it with an ohmmeter. It always could
be an high resistance in the winding in the motor itself, but unlikely
because the motor IS turning in both directions - and you would see that
with an ohmmeter. Mechanical issues would show up in both directions after a
few operations.
The rotator circuitry is symmetric in one direction as compared to the
other. You can swap pins 5 and 6 at the controller to make the rotator turn
in the opposite direction than the lever you push, if you want to quickly
determine if the problem is in the control head or the rotator. Be sure and
swap them back when you're done or you will get very confused.
I prefer to use my trusty DVM.
Good luck, Allen.
