   No sign of either. I just pulled out the circuit board, and no visual   
   sign of damage. The diodes and cap on the power input to the board test OK.

   Kind of weird. It worked one day, but not at all the following morning.

   I measured across the wires going toward the power cord for the primary,   
   and the wires going to the circuit board for the secondary. 2 pairs of   
   wires completely different wires, one pair from each side.   
      
   I moved a system that used to be used in my exercise room up, and it fit   
   in my space, so no crisis. Maybe I will try unwinding the transformer   
   coil some time I'm feeling bored.
