Hy Streamylc, what year truck are we talking about? Six volt tags have a black background, twelve volt tags have a red background. I don't think any twelve volt generators have the brush cover strap on them, hope that helps.
Oops. I'm sorry :-P
'57 Chevy 4400.
Yup, mine is red background with white lettering.
I assume this means the system HAS to be 12v right?
