How can I tell if a generator is 12 or 6 volt?

What happens if I run a 6 volt on a 12 volt system?

black tag = 6V, red tag = 12V

if you've got a 12V battery it won't get charged

If the tags are missing examine the generator body if it has been rebuilt shops often stamp the voltage on.

No tags, no stamp.

I'll just leave it on the engine when I do the swap. Then put a meter on it and see what happens.

There should be a number stamped into the body. Somewhere I have a Delco document that lists the numbers. I used it to identify a 12 volt that I bought.

Numbers stamped onto the case may not provide the definitive answer. ClassicGenerator recently built a generator for my '54 using a correct 6v case with 12v guts inside.
