Re: Generator question

[frankr]

It needs to be polarized. To bench test and polarize at the same time:
1. Use a jumper wire to ground the field terminal (the small one) to the case.
2. Use another wire to ground the case to a 12V battery negative post.
3. Use a third wire to connect the armature terminal (the larger one) to 12V battery positive post.

With the above hookup, the generator should run slowly like a motor. This also polarizes the generator.
