It does turn over, and the previous owner said it had "wiring problems". First order of business is determining if it is 6 or 12 volt. I'm leaning toward 12 volt because the battery is 12 volt - but not taking any chances. Any help in determining is appreciated.

Are you referring to a 2-ton GMC or Chevrolet truck?
Most likely you have a 1955 second-series Chevrolet truck and it is most likely 12v.
If the generator or starter have a Delco-Remy tag on them, red is 12v and black is 6v.

The operating voltage is embosed right on the
glass lense..... | | | | | Joined: Mar 2011 Posts: 32 'Bolter | | 'Bolter Joined: Mar 2011 Posts: 32 | It's a 12 volt - thanks everyone. | | |
