In order for the generator to charge, the armature has to have the correct polarity in respect to the field coils. SO....you take a wire and "spark" the armature terminal from the POS battery terminal. That gives the generator the correct polarity. If you don't spark or polarize it, it won't charge. Chuck

Ok here goes. Its a very simple procedure. After installing the generator and hooking up all of the leads, but before starting, it is necessary to polarize the generator. The polarizing procedure is different depending on whether the field is internally or externally grounded. Since I'm assuming you are working on a C1 I know that the generator is of the externally grounded variety and the following procedure should be followed. Get yourself a jumper wire and momentarily connect the jumper from the Bat. to the Gen. or Arm. terminal on the voltage regulator. Just a momentary contact (1/2 second) is required. That's all there is to it. :smash: :steering:

I just replaced the alternator on my 64 but did not polarize it. It appears to work fine but is this something that I needed to do and should always do if alternators are changed? Is the procedure the same. thanks -----Jim :seeya

Jimbo64, You do not have to polorize an alternator, just a generator.

Tom thanks for the quick reply. With me, each bit of information is an educational
thing as I'm learning. Guess that will go on as long as I tinker. Have a great day> :cheers:

If you don't polarize the generator, there is a 50/50 chance it will work correctly anyway. It's a good idea to follow the proceedure any time any of the components in the charging system are changed or disconnected.

Folks,

I will be putting in a rebuilt generator into my '59 Vette. Just wnat to ensure that I don't mess up the polarizing of the gen. The jumper cable would be connected to the positive pole on the battery to which of the three on the generator? I am assuming that the one on the top is the correct one (the one with the round warning tag).

Please confirm before I cause more damage :-)

Thanks,

Jan

You can do it with a short jumper right at the voltage regulator -- these are the instructions (in the red stripe at the top) right off the regulator.

when replacing a voltage regulator. does the regulator need to be polarized with an alternator in system?

You polarize the GENERATOR not the REGULATOR so, no, if you have an alternator -- no polarization required...

Its a big confusing since you can polarize the generator at the V/R terminals...

I like to polarize a generator by tossing it in the nearest large body of water, If it floats back up its polarized and good to go.

If it doesnt I install an alternator and never worry again.

I never worry with my generator....never had it off the car; never had to touch it yet....
and it runs my 600W Kenwood radio amplifier just fine...

You're right. Generators suk and are a maintenance nightmare. In fact, I've actually had to replace the brushes in mine, ONCE IN 35 YEARS. My suggestion is, tie 1000 generators to your body and jump in that same body of water. If you float back up, you're NOT an idiot. There are millions of cars running generators that have zero problems.

Rebuilt my original generator once 20 + years ago and never had to touch it since. As for polarizing, key on, small flat blade screw driver across the two terminals of the regulator momentarily and your done. Those without training as a rocket scientist need not worry. Pilot Dan
