I have what seems to be a common issue. Battery Drain!!

Thanks to all of the wonderfrul information already posted, I should be good to go with troubleshooting.

But I have one question. In all of the posts I have read, the car must be in normal shutdown mode about 16 min after you turn it off.

Is there any switch for the hood that would need to be turned off so I can troubleshoot with it open? I have a 1992 525i Wagon, if that helps.

Thanks in advance for any help.
