: The car is a '79 633CSi. The battery was dead a few weeks ago (strange, because it was only 18 months old, but maybe I left the interior lights on...). Anyway, I replaces the battery today and cleaned up a few other connections, then fired it up. After warm-up, I ran up the street and back and noticed that the temperature gauge was responding to electrical load (i.e. would swing up when I hit the brakes, hit a window switch, or even engaged the back-up lamps). I also notice that the voltage/alternator (?) lamp is glowing very very weakly, only really noticable when the interior is dark (night or very early morning)and did before the previous battery went bad. Are these inter-related? Is the dim glow telling me the alternator isn't putting out, or perhaps a regulator problem? How about that temp gauge - I'd rather have it read engine temp than electrical load. Any and all help/advice is greatly appreciated. Many thanks.


Check the Chassis ground strap from the battery to the frame and the engine to the frame. I have had similar woes on othe cars and this was the problem.
Don't worry about the "dash battery", I can only speak to my '79, but I don't think the E12 based chassis used one.
