Our 1972 Chevrolet Blazer had some intermittent ignition problems, so we called in Dave Welch, the expert in Classic Trucks to help us sort it out. Dave removed the switch, diagnosed the wiring problems and shorted switch, repaired the wiring and replaced the ignition plug and ultimately the bad switch too.
