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 #2 voltage sensing terminal allows the voltage regulator to. Hello. today i show you how to wire a 10si one wire three wire alternator to a diesel farm tractor. this method makes the alternator start charging as soon a.
