According to John Deere Pin 4 of the JD 20 amp regulator is for a charging light but has been called an idiot light too. Which is it cause they ain't the same thing? I do have a voltage alarm module set for 11.5 volts to indicate a failed generator so If pin 4 does not need to be hooked up I will just leave it blank.
