Polarize Generator Some gearhead somewhere is always wonderin about the need to polarize a generator. If the generator is charging...ya know...(the battery stays charged) then you don't have to hassle with this stuff. But... if your generator has been sittin around unused for a long time (months or years), the metal core looses it's magnetism, and it NEEDS a little residual magnetism to start the charging process. So this is how I go about it: To polarize a generator, Connect a jumper wire from the (DF) terminal on the generator to the generator frame. Remove the fan belt, then connect a wire from the positive terminal on the battery to the (D+) terminal on the generator. The generator shaft should start to spin. The generator will now be properly polarized Polarizing just gives it enough "boost" in magnetism to start it charging properly. When it's being used, it keeps its core polarized core so no need to do it again. Polarization is a simple process used to restore the field pole residual magnetism and ensure the magnetic direction is correct. Note: Don't run the generator this way for more than a few seconds, ya don't want to fry anything. |
