Does anyone have a map of the charging system for the evo. My evo wont charge itself. It will stay at 12.5 volts no matter what. It will continue to run at 12.5 until you leave it and it will slowly drain until it will not start anymore. Of course when you put more draw on it, like turn the headlights on it immediatley drops more, sometimes into the 11's. I thought it was the alternator so I went and bought a new one from mitsu, but it still does the same thing.
