Re: polarizing the generator?

Some more thought here:

If you started the engine and your GEN light went out then probably there is no reason to re-polarize the generator.

If the generator is polarized backwards it usually won't charge the battery at all. If it is polarized correct it won't improve by being re-polarized. It either works or not.

Keeping in mind some cars were positive ground (Like my Packard) and some negative ground.

My model T Ford is Neg ground and I screwed many an Ammeter before I figured out how to properly polarize the generator.

Once polarized the generator stays that way until somebody causes it to change. They don't change on their own.

The regulator which you should not mess with unless you know what you are doing and have accurate Volt and Amp meters regulates charging voltage as well as current as well as provides the cutout.

The generator on my 54 just keeps up with the radio, headlights, and heater on at idle, The GEN light just flickers dim just after I crank the starter but stays off after a minute or two.
