Polarizing a generator only requires an instantaneous connection. Longer than that accomplishes nothing. Polarizing the generator simply instills a small amount of permanent magnetism of the proper orientation in the field assemblies.

If a generator should have been polarized and wasn't it won't show a charge. If it shows a charge then the polariztion is correct.

The polarity of the coil should be such that the coil terminal that goes to the distributor is the same as the battery ground.
