It sounds like the switch on the pedal is done or has lost a good connection. Should be pretty easy to fix. First, disconnect the TM from the battery. Next see if you can feel the switch. When you put your foot on it, there is a point where you will feel a click. If the click is there, tip over the foot pedal and take some pictures. Then look for loose wires. Most the time some wires have gotten a build up on them. If you find one, take a scotch bright pad or a fine sandpaper and clean it and reconnect. Hope this helps.
