Several persons looking at me, older semi truck drivers, slowed down to look. But got new problems today. Drove the truck to Arrowhead and watched my tigers win. Got in the truck and it wouldn't start. Pushed it , wouldn't start. Jumped it and it sstarted. Drove it home with friends in front and back , lights went out about 3/4 of the way home. Then people honked at me for no lights. Parked it in my driveway, tried to start it and it was drained of energy. Have a short somewhere. Why doesn't my alternator charge the battery when running//Oh old trucks
