i have a 79 320i and earlier i posted a message on this board about my headlights only working if my high beams are on and they told me it was the low beam realy. i havent had a chance to get a low beam realy...actually i cant find one where i live. also when i am driving at night with my high beams on, my fan on, and my cd player on, the temp gage goes way up.....almost to the end, but if i shut off the fan and lights it instantly goes back down to normal, also when i turn on my turn signal, my temp gage does a little dance bouncing back and forth in time to the click of the turn signal. is this happening because my cd player is draining my battery? or what else could it be?
