Linear accelerator assembly part # 122420. By card, I mean the oscillator card in the SCR panel. TB11-1 is input from sevcon controller. 3.7 with key "on" smooth decrease in voltage to.5 with pedal all the way to floorboard. (at distribution board) check voltage at CA208 #1 for battery voltage. after accel pedal is pressed, batt volts should go to CA208 #2. Test with seat switch closed and directional control in forward. It's a bit tricky if you're unfamiliar with it and especially if its intermintent. You have a manual?? A switch would if its not closing or closing to early. Good luck, eh. if switch passes voltage and card receives proper voltage swipe at tb11-1, then your card is at fault (meaning oscillator in EV100 panel)
