power drain in my 84 633

Pleas help. Something in my electrical is doing a slow drain on my battery. If the car sits for more than 2 days, the battery is dead. I've already replaced the battery, and have gone thru the car to no avail. Has any one else experienced this. the electronics are all stock, except for the stereo, which the previous owner installed.

There is only one way to find the drain, you need to get an amp meter.

There was a BMW recall to wire the glove box and trunk lights to be ignition controlled to prevent the drain possibilities.
