Some aftermarket housings are not marked and others may be worn off. So if your alternator housing is unmarked, look from the rear of the alternator: the #1 terminal is on the left and the #2 on the right. You only need an ignition wire to the #1 terminal to make an Si series alternator work. The #2 terminal is for voltage sensing, and is optional.. The Delco Remy 3-wire alternator wiring diagram consists of three main connections: the Batt terminal, the S terminal, and the F terminal. The Batt terminal is connected directly to the battery positive terminal and provides the main charging power for the alternator. The S terminal is connected to the ignition switch and serves as a voltage.
