Following up on my query from a week ago: 1950 GMC 150, trying to track down an electrical gremlin. I replaced the original headlight switch with a new remanufactured one, but when I engage the last stop on the switch--which should turn on the headlights--the engine cuts out. The other lights--stop, parking, turn signals--work fine. So the new switch has fixed most issues, but I am at a loss about the headlight thing. Could something be wrong with the ammeter?
