Start the engine and set it to a fast idle, then jump across the two cutout terminals. If it now shows a charge the cutout needs the contacts cleaned, or the pull in winding is bad. If the amp guage still shows a charge after the jumper wire is removed, then the generator just needed to be polarized.

Don't run a Model A generator for more than a few seconds if it's not connected to the battery, or it may burn itself up. If the cutout is faulty, then the generator isn't connected to the battery. In case of a faulty cutout, you can safely run the generator by jumping the output post to ground.
