This morning I found my G-5500 will not move left or right. Not even a wiggle. Took some measurements and the wiring appears to be intact but I don't understand the 40 Vac readings when the rotor is connected to the control box. Here are my readings taken at the control box end of the wiring:
Rotor connected to control box:
Common (pin 6) to Left (pin 4) Press Left: 28 Vac Right: 40 Vac
Common (pin 6) to Right (pin 5) Press Left: 40 Vac Right: 28 Vac
Rotor disconnected. Measuring control box terminals:
Pin 6 to 4 Press Left: 29.5 Vac Press right: 0
Pin 6 to 5 Press Left: 0 Press Right: 29.5 Vac
Measuring rotor cable at control box, disconnected from box:
6 (brown) to 4 (blue) 5.3 Ohms
6 (brown) to 5 (orange) 5.3 Ohms
4 (blue) to 5 (orange) 8.9 Ohms
Any suggestions before I pull the rotor off the mast?

Oh, nooo!!! Your SatGate is really important in the North West. I hope the remedy is not too complicated. 73 Robert MacHale. KE6BLR Ham Radio License. http://spaceCommunicator.club/aprs%C2%A0 . Supporting Boy Scout Merit Badges in Radio, Robotics, and Space Exploration
