I have had the 61D for several years and it was worked well. It is turning an
original SteppIR MonstIR. I have a Green Heron RT-21 with the GH pot in the
661D. The other day when I went to turn the antenna nothing happened.I tried
using a 12V supply. Same problem.When I try to turn the antenna, I get an
"ERROR NO MOTION" .Current draw is 400mA.I am feeding the rotator with three
#14 wires for CW, CCW and GND.Since this problem occurred, the antenna has been
slowly moving in the wind from 280 degrees to 231 degrees - both actual
movement and reading on the controller match. My thought is the motor's worm
gear is not engaged so therefore it can't act like a bake. Is it possible the
motor is running fine but not engaged with the pinion gear? Is 400mA the
correct current?
Any thoughts or ideas before I climb?ThanksN2TK, Tony
