POLARIZING A & B Type GENERATORS
______________________________________________________
Type "A" circuit - The field winding is connected to the insulated brush inside the generator and is connected to ground through the contact points in the regulator.
Type "B" circuit - The field winding is grounded inside the generator and is conncted to the armature circut inside the regulator.
To polarize the generator with:
Type "A" circuit - Momentarily connect a jumper lead between the regulator BATTERY and ARMATURE terminals after all leads have been connected, but before the engine is started.
Type "B" circuit - Disconnect the lead from the regulator FIELD terminal, and momentarily touch the lead to the regulator BATTERY terminal. This should be done after all other leads have been connected and before the engine is started.
I have always followed Bruce's way (Type "B") with good results with 1960-61-62 ford 12 volt generators
