six volt generator polarization

[robert feldman]

Hello All,

 

I installed a used but good generator on my '42 Dodge. What is the procedure for polarizing the generator on this vehicle. It is a 6 volt positive ground.

 

Thank you in advance,

 

 

Don

EDIT: You may or may not need to polarize the generator. If the battery is in right, amp meter hooked up correctly, and you get a + indication on the amp meter when you run up the rpm's, you are good to go.

 

EDIT 2: welcome to the forum, and site

Polarization restores the residual magnetism in the cores of the generator field poles so that when the generator starts charging it will do so in the proper polarity.

It is usually not necessary to re-polarize unless the generator has been removed and repaired or the regulator has been changed. If this has occured, then re-polarization should be done before starting the engine. Otherwise, the generator may not charge or it could charge in the reverse direction.

Re-polarizing is relatively easy to do. All that is necessary is to briefly connect the generator armature to the battery hot terminal. The most convenient way to do this is to take a short jumper wire and touch it to the "Batt" and "Gen" terminals on the voltage regulator. At the moment of contact you should see a slight spark. This indicates that the process is completed.

It should be noted that it is the generator that is being polarized, not the regulator.

Thank you Navy boy. I'm deducing that the gen and armature terminals are one and the same?
