    while your car is running take the batery cables off, if your car turns off its the alternator, also check all your fuses (sometimes we forget about the little things

    Sounds like its your Voltage Regulator on your alternator rather then a prob with the diodes or field coils.

    what voltage are you reading with the car running? it should be around 14.4v, if it goes up over 15v when you rev it then it definitely you voltage regulator.
