Unfortunately, I can't hear the rotor from the ground. It is about 70
ft in the air.

Barry, while the brake is released, can you detect any hum from the motor
indicating it is trying to turn? If yes, then you probably have a brake
problem.
All there is are the 4 springs and the pin that could be wrong. ( I think )
otherwise I would check my wiring - two or three times very carefully. The
motors are normally fairly resistant to failure. G,luk / Dave / NØATH

I have a sick tailtwister. It won't rotate either CW or CCW. I checked
the fuses, OK. I measured the voltage at the control unit with the cable
disconnected as per the manual, Voltages=OK. I measured the pin to pin
resistances as per the manual, resistances= OK. I tried a new motor start
capacitor, Nothing/ No Rotation. I can hear the solenoid click when I
depress the brake switch. With cable attached, brake button pushed and CW
pushed, I read about 18.4 VAC on the two terminals. About the same voltage
on the other two terminals with the bake button pushed and the CCW button
pushed.
I'm beginning to wonder if the brake mechanism might be broken. But,
before I take the tower down (it is a fold over), I would like to be sure
that I have checked everything that I can from the ground.
Any ideas?
