My '53 1/2 Ton's 6v fuel gauge appears to be working properly- but a few days ago I noticed that even after I remove the key it just stays on. It just reads whatever the gas level is. I disconnect the battery if I leave it overnight.

Any ideas on what could've happened?

Or is this normal and I've just been blind for the three years Ive been driving it??
