    1977 K10 generator light quit working not exciting alternator

    Yeah it has a red wire and ground wire although the ground appears to be odd which is why I believe the bulb holder is my issue im going to purchase a 194 bulb holder such as this I believe that will work correctly and I can probably make it fit in the back of the cluster where the gen light is...

    1977 K10 generator light quit working not exciting alternator

    I think I understand now you run 12v to the hot wire of the bulb and the ground to the terminal 1 alternator is the ground until it is excited essentially once that happens it loses the ground lights goes out
