YES!  You have 3 wires going up to the ele rotor.  They are labeled E-4.
E-5, and E-6.  E-6 is your common.  E-4 is your down line, and E-5 is your
up line.

Connect a DMM as close to the rotor as you can get, like the terminals on
the rotor, and have someone in the shack push the buttons.  Test the voltage
going up, E-5 red and E-6 black DMM leads.  They move the red lead to E-4
and have them press down.  If the readings from E-5 and E-4 are the same, it
is your rotor.  If not, it is wiring.  You already eliminated the control
box.

Good luck - hope this is the answer you were looking for.

Mike.
