Changing to a One-Wire Alternator from a Three-Wire, Part 1
On early ’60s cars and trucks with an external voltage regulator, this change is a bit more complicated than later models. Disconnect the wiring from the voltage regulator and discard the wires going to the alternator. Leave the alternator output wire intact. Remove the ignition wire coming from the main harness to the regulator, usually a brown wire, from the regulator connector tape
and secure. Discard the connector. Caution: The factory output wire on the old alternator will probably be too small to carry the high-amperage output of the new alternator. An add-on charge wire kit like the Painless PN 30709
Note: A charge light can’t be used with a
one-wire alternator system.
