      I would venture to say that a 240V to 12V transformer that was inadvertently
      plugged into 120V would output 6V.

      240/12= 20.........therefore 20:1 Ratio
      120/6 = 20.........therefore 20:1 Ratio

      But I don't have knowledge as to what happens further down the circuit but
      I'd guess, nothing...
      But you say it has stopped working so something must have happened.

      Wish I could help, sorry.

      Looking Up,

      The hand controller checks out. So the question is - has it done something
      to the RA/DEC motors or simply just burned out a fuse. To recap:

      1) Plugged a 240V transformer into 110V
      2) This would mean that 12V not exiting transformer
