My throttle got stuck open on my 76 2002. Its all stock 80,000 og miles. Runs strong, everything works. However when it was stuck open it made a strange grinding sound so I pulled over, at the same time noticing the turn signals, and windshield wipers didn't work. Horn didn't work either. Ofcourse I started checking other electrical components when the first two quit. After I figured out where the grinding came from, (the carb) I unstuck the throttle and all electrical components work once again. Any insight on this or is it a strange coincedence? Help me with my spelling also if anybody has the heart.
