I have a 1951 Hudson Hornet with the stock 5 volt system. I typically unplug the battery when its not in use. I've been told that if I do that, I need to polarize the generator and/or the regulator. It would be appreciated if I could get some comments to help me understand the polarization process and why its done. Then, perhaps some comments on whether these items need to be polarized when the battery has been unhooked from the leads. Thanks.
