Any body out there have a problem with the headlights being just too dim? I have a 100 amp one-wire alternator, the only electrical items being twin electric fans and an electric fuel pump. Optima red top battery trunk mounted. Is this a pretty common problem? I guess I could start by measuring by the lights making sure there is a true 12 volts. Or, is there something common to look at in G-bodies specifically? I have an Autometer voltage gauge, and when driving around town, it reads around 14 volts. I think that's fine, but why the dim headlights? Thanks to all that respond!
