I have a 1983 300D, and when I started the car this morning and turned on the headlights both turn signal lamps came on in the dash, along with the seatbelt and glow plug lamps lighting up dimly, and my tape deck clicking many times as if ejecting a tape rapidly. Checked all my fuses and they are fine. Also appears only to happen when the gear selector is in any position rather than park. I am thinking perhaps an alternator problem, but wanted some feedback from other diesel Benz enthusiasts. Thanks for any help.
