ok, in my 79, whenever i turn on the lights, my gas gauge doesnt work. for a year ive had my twilight sentinel on so i thought my sending unit broke and just put gas in it every 5 days. but now it actually works, just the lights have to be off. any reason why? like, when i turn on the lights, the damn needle falls. with twilight on, it never comes on.
