Measure voltage between terminal 49 and 46.
If it is 15-17 volts, the jack shorting contacts are open or a wire between the jack and 46 or 49.
If you have 15-17volts between 49 and 46, try clipping a jumper between 46 and 49 to verify that the solenoid is working. A more likely cause of the jack shorting contacts now working is non-use rather than burning.
Inserting a footswitch should be able to control the solenoid even if the shorting contacts are corroded. A little DeOxit and exercising the jack should take care of that problem.
