OK OT mechanics. What's wrong here. I have a 3 series '94 BMW. I'll get in the car and it'll act like the battery is disconnected. I don't think it's the alternator because there's absolutley no power, plus I had a new alternator installed about 1 year ago. No lights, no radio, no engine cranking, no nothing. Then all of a sudden, after trying to start it many times, it'll just start with no problem. The radio and time are all reset. Any ideas? Since it sounds electrical, do you think I need to take it to a BMW specialist? Or might it be common enough where I can take it to a regular mechanic?
