I have a fairly new antenna rotor (about 2 years old). The box is turning the dial, but the antenna is not rotating. The wire connections are ok on the control box, so I assume a wire broke at the motor from wind. However, before I go on the roof, I want to test the voltage output at the control terminals. What should I expect for voltage, and is it AC or DC?
I should also mention that it's about zero deg. outdoors, and was wondering if all or most rotors simply will not turn when it's this cold. Anyone know?
And, lets say that I am seeing power at the control box. Can a meter on the resistance range show whether I have a connection both inside and outside the rotor motor. (in other words, show the motor windings). Being this frikkin cold outdoors, I want to do as much testing from indoors first......
BTW It's a THREE wire type (I know some have four) I cant tell you the brans, because it's not on the control box (duh....)
Thanks
