Polarizing

Why: To insure the direction of current flow is to the battery. Incorrect current flow will add the voltages of the generator and battery, and give approximately double voltage across the points of the cutout relay in the regulator. The result: rundown battery, burned or welded together points, and a burnt armature.

When: Anytime battery voltage is removed from the generator; after repair, removal for testing, battery replacement, or use of battery cutoff switch.

How: By connecting jumper lead from hot side of battery to the armature (connecting battery terminal of reg to "A" or "G" terminal). A flash or arc is a normal occurrence during this process.
