Hi, I replaced the switch, but that didn't work. I have good continuity between the engine and chassis, looked for bad, rusty, or corroded grounds and guess what, it was the voltage regulator. My dad has a 1973 chiltons covering cars from 1966 to 1973. It tells how to check the voltage regulator and when we checked it it was bad. Never again will I buy stuff from NAPA!!!
