Re: polarizing a generator
Any electrical coil has a magnetic field around it when energized and some may be retained.. Generally a generator shouldn't lose polarity unless the field coils are removed,but, stuff happens.. If its lost, it needs to be replaced.. Just attach a short jumper wire across the cut-out terminals.. Just a flash/second will do..

Re: polarizing a generator
Polarizing a generator is telling the gen. how the battery is hooked up. Positive or negative ground. It is done by using a short piece of wire and touching the post coming out of the generator(which is connected to one side of the cutout switch, and holding the wire to the otherside of the cutout switch, for about 3 seconds. You will see a slight spark when you first touch the terminals. The wire on the other side goes to the battery and thus the generator sees which way current needs to flow.

Re: polarizing a generator
If I understand the theory correctly, you can take a car that is as delivered by Henry with a positive ground 6-volt system and turn the battery around so that the system is now a negative ground, flash the generator, and it will now put out a positive voltage instead of a negative voltage. I always thought the generator had to be rewired in order to produce a positive output.

I don't mean to highjack this thread, but Tom I think you answered a question that has been bugging me for a while. I want to try and run a 1936 Chevy Delco-Remy generator that I rebuilt on my '31 "A". Some time ago I acquired an old aftermarket accessory bracket that will let me do this. So all I will need to do is attach the Delco generator (with a Delco cut-out), polarize it and I will be good to go? TIA Bob-A |
