      I have another that's a closer match to the original on the way . In   
   the meanwhile I can still use the machine if I need to . While I have   
   the pedal apart for I think I'll check the resistance of the leads in   
   the cable .

   High resistance is most likely to be in connections, though wire can corrode   
   if water gets in through insulation damage.   
      
   The current limited by a headlight bulb is enough to measure wire   
   resistance. It may be between 5 and 10 Amps so be careful how you measure   
   it. The 10A range on some DVMs has a time limit.   
      
   Electric water heater elements have resistance in the low tens of Ohms and   
   can serve as current limiters, with the advantage of screw terminals. Like   
   light bulb filaments, heating element resistance changes with temperature so   
   you can't measure the cold resistance and then compute current from voltage   
   drop. The resistance change for Nichrome is low but you can't assume it's   
   used.   
      
   I make homebrew current shunts to repair old ammeters with Constantan from   
   Type T thermocouple wire.
