hey guys this is my first thread. i have a 79 and my gen light alawys comes on after the car is warmed up. my car never dies so i'm pretty sure it's still charging my battery but not sure if it means its going bad or what. has anyone had this happen to them? and as well as my rear diff light, that one is always on. i'm guessing thats a level sensor. is that right?
