                                well produced video about your electrical charging 
                                system. It begins with a fundamental explanation 
                                of electrical theory. Afterwards the components 
                                of the system are explained including the alternator, 
                                alternator control unit (ACU), voltage regulators, 
                                batteries, belts, connections, switches, and circuit 
                                breakers. Then, three primary failure modes are 
                                discussed (dead battery, undervoltage during run-up, 
                                and overvoltage conditions) along with their symptoms, 
                                likely causes, and fixes. Even, if your system 
                                has been trouble free, this video does a good 
                                job of explaining its functions and will help 
                                you to understand how to properly monitor it for 
                                early signs of problems. Albeit, 
                                  since the announcer is somewhat of a fast talker, 
                                  you will probably need to run it 2-3 times to 
                                  get a full understanding of the subject.
