Battery drain - fog lights to blame?

thanks -- I'll be sure to limit my advice on this issue to '84 and newer 911s going forward

I knew it was too good to be true.

Does the relay drop the window a bit and then lift it back up to seal it up tight in the door after it shuts? I don't remember seeing that on cars until the 1990's.

No, it simply leaves the window circuit active so you can roll up the windows after turning off the ignition, but before opening the door.

I just went through this earlier in the year (Battery Drain in 87 Cabriolet (Or Not?)) and the problem was indeed the power window relay being energized all the time, though not for the typical reason. In the process of fixing this issue I resolved a fuel-pump-always-runs issue as well. Lucky for me I like solving puzzles and got some excellent support from knowledgeable Pelicans. Like everything else I've done to the car, going through the process was a great learning experience.

Since then I've gone weeks without starting or charging the car with barely detectable drain on the battery.

Good luck!

Not a dead end. Just another learning opportunity.

Now there are a handful of folks that have this new knowledge.
