Hey Forum, just had a quick question. I just replaced the batter in my car, but I know the alternator isn't working. I'm in the course of replacing the alternator but it hasn't shipped yet. I was in the course of messing around with other things in the car and noticed that the headlights aren't popping up anymore. I know that the alternator recharges the battery, and in my case, isn't happening right now. Are the headlights not popping because I have ran the battery down to a less than required voltage to pop open the headlights?

Thanks for reading my ramble,
~Drizz

I have a '79 924, I'll have to get back to you on the battery voltage/amps.

EDIT: The battery is a Duralast 48-DL, Cranking Amps 875, Cold Cranking Amps 700, Reserve Capacity 115

I just don't understand if the headlights are directly related to the current voltage of the battery, if they are, it would make sense due to the alternator being faulty.

It WAS working, I flipped the lights off, then went to hit them back on...and they didn't pop back up. Think I might have blown a fuse?

Edit: The fog lights were working while the headlights were not, not neither work. It almost seems like it is battery related, unless headlights/flood lights run off the same fuse.

I also have a 79' 924 and it has the same problem, just the lights dont go down. The lights still work and all, and I also thought it was an alternator/battery problem. Most of the problems with my car have been alternator/battery related, so it wouldn't surprise me if that was it.

The circuit to control the light movement is a tad complex and relies on a wheel on the end of the motor with three contacts. These can go a bit agly, but before you go to the trouble of dismantling it (not difficult, just takes a bit of time), check the socket plugging into the motor has all it's pins making contact. All it takes is for one to be loose and it doesn't work right.
