well, in a car with alternator, there is a voltage recgulator and a alternator brush. The alternator brush is usually what needs to be replaced. THe rectifier is basically what that is in a sense (not really tho). but i would def go to the dealership and tell them that its not chraging due to the rectifier and ask them how much is it going to be replaced. Or if u have a hanynes manual, see how hard it is to do urself. buy the part and see if that fixes it. I don't believe that any other wires such as the kill switch n everything might come into play since u are testing this over the battery terminals. then again, i might be wrong. I would check to see if the wires to the stator/rotor are ok. rectifier should be a cheap part, but then again, its the labor that is expensive.
