Generator Polarity

If the regulator or generator wires are disconnected, or when changing the battery, observe the following instructions in order to avoid the possibility of reversing polarity of the generator, thus vibrating and burning the cut-out relay contacts.

See that the positive side of the battery is grounded (positive ground systems). The cable from "F" (Field) terminal on the generator must be connected to the "F" terminal on the regulator. (See above.) The cable from the "A" (Armature) terminal on the generator must be connected to the "GEN" (Generator) terminal on the regulator. The cable from the "BAT" (Battery) terminal on the regulator must be connected to the ammeter. Then, before starting the engine, momentarily touch the lead (or use a screwdriver) from the "GEN" terminal to the "BAT" terminal on the regulator. The surge of the battery current to the generator will correctly polarize the generator.

Note: The terminal positions on the Delco current and voltage regulators differ from those on the Autolite regulators. The Autolite terminals are marked beneath the terminals on the base plate.
