Original Alternator Connections

Once you really look at the back of the alternator installed on our coaches you will see these two connections. One is the Ringed Output cable that is bolted to the Output stud. The other connector is a two wire connector that houses the voltage sense wire, and the "Gen" dash light. ( This is also the Alternator "Start"or exciter circuit conductor ) For a full description on how the Alternator actually works, please refer to the this photo description in John Heslinga's Alternator Repair Album:
