On the plug on the external regulator unplug it an find the hot wire; this is the "BAT" wire which you will need to run to the big threaded terminal on the back of the alternator. Run a short jumper from the #2 side spade terminal to the same terminal. The #1 side terminal will go to the idiot light or if gauges it can be used to excite the alternator upon starting. Run this wire from the ACCESSORY side of the ignition switch and NOT from the ignition side as the engine won't turn off. If charging current is flowing through the original "BAT" wire the gauge won't know if it's from a generator, alternator of any type, or a gerbil spinning a miniature turbine.
