    Flashing the field

    On my '60 I thought I was having elec problems. I removed the gen and volt reg and had them checked out and all was fine. Replaced the battery. After starting, the Ammeter showed a discharge (5-10). When I turned on the headlights it went further discharge so I don't think it's wired backwards. Someone mentioned "flashing the field" but I don't know what that is or how to do it or if it might help. Any thoughts on the subject would be appreciated.

    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.

      Yes, and the "inapplicability" of this procedure to cars with alternators is just one of the reasons that alternators are so superior to generators.

            Note that the jumper lead is BRIEFLY shunted between the terminals. A flash should be seen and/or heard. On the Corvette, with the regulator mounted in the original position on the fender well, the two bottom terminals on the regulator are the ones to jump out - just a touch is all you need.
