So I'm in the process of swapping to 12v and was going to use the pulley from the generator to put on the alternator. Anybody done this? I'm having an issue where all it wants to do is spin. I've taken it apart, but am not sure that I want to clamp it down in a vise for fear of breaking it. I would like to be able to take it to a swap meet or sell it because it still works.
