Hello there.
I have a 51 chevy with a 6 volt system that I do no want to change.
I want to install a 12 volt radio and 12 volt fog lights. I would like to know what I have to do and where to get the parts. Any information would be appriceated. Thanks Grease Monkey 123

If the 12-volt radio is transistorized you can purchase a voltage booster. The power of the booster is limited, but should do okay for the radio.

The fog lights are a different story. Don't know what fog light you are talking about, but the simple way for the light is to remove the 12-volt bulb and replace it with a 6-volt bulb. The 12-volt lights require much more power to operate than what the booster device can handle.

Hi Ray'
Thanks for the reply and the info. Where would I purchase a booster for that radio? Grease monkey 123

Chev's of the 40s and possibly the Filling Station.

If you don't have any luck let me know and I will provide a positive source.
