Nat,
To tell you the truth, I have never heard that; of course that "begs the
question" as to why the "ground" screw is on the control box and the rotor
connector if you are not suppose to use it. Additionally, if it was a "big
deal", why would the installation instructions not mention that and inform
one on how to do it correctly?
The only "non-standard" rotor hook up that I know of (that is not published
anywhere that I know of) concerns Ham Ms and Tailtwisters. The "change"
involves mounting the motor run capacitor in a box by the rotor, and not use
the one in the control box. There are two advantages to doing this; first,
the capacitor is right by the motor (where it should be for best
efficiency). And second, that "frees up" the two wires going to the
capacitor in the rotor box to now be paralleled with the motor run wires;
that results in less voltage drop at the motor, and better efficiency.
In any case, it will be interesting to hear what the rational is concerning
the ground wire.

Hi All.
Today the rotor and control box were both swapped out and everything is
behaving as expected. The were no defects in wiring inside the little box at
the rotor. So something internal must have died. I am awaiting clinical
results from M2. M2 really came out ahead in the customer service
department. Kudos!
One thing mentioned by the installer that was of interest was to not use the
ground connection in the rotor cable. Anyone else familiar with this?
Thanks for the bandwidth.
