If so, in all likelihood it will charge and therefore consider swapping out and installing a good Cut-out with a diode in it.

If you apply voltage to a generator it will try to work as a motor. This is the reason for the cutout, it cuts the generator out when the engine is not moving (or moving fast).
If it doesn't motor it is an almost guarantee that the genny is bad. Like Brent says in all likelihood the genny will work. Next step after the genny motors is to follow Toms advice;
[quote]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 gauge still shows a charge after the jumper wire is removed, then the generator just needed to be polarized.[/unquote]
This actually does two things, bypasses the cutout, and polarizes the generator. WARNING if you have a regulator in a can and not a cutout you will damage the regulator.
Just wanted to put all the steps in one post with a little explanation.
