I've had this old machine for a long time and it has never failed me...until now. Step on the pedal and all I get is a tiny spark. I took the remote cord off and found the strain relief on the connector was loose. When I took the connector apart I found broken wires. Not real surprising considering how often the foot pedal is yanked to it's extreme length. What a PIA to solder the wires back on the pins. All is good now, but just wanted to give a heads-up to check the connectors so you don't have to go through the same problem.
