I have read most of the posts here on the battery drain issue and I know it has a long history.
I know that if I remove the room fuse the battery does not drain.
I do have the correct ETACS and antenna fuse was in while room fuse was out. Some say power antenna can cause this issue.
Question is, has anyone ever documented what goes through the room fuse? ( apparently quite a bit).
And has anyone found a particular component that runs through the room fuse that caused battery drain?

Thanks

I haven't run into a problem with battery drain. Check what doesn't work when the room fuse is out. Make a list, then disconnect everything. Install the room fuse, and reconnect one thing at a time to see what may be causing the drain.

Basically the same as doing a vampire drain just in reverse.

Original etacs in the 87s drained the battery. I know its in here somewhere

There was a known defect in the earlier ones. They put out an updated ETACS for 87 that fixed the problem.

Yes but as stated above mine has the updated ETACS, I pulled it anyway as part of troubleshooting and battery still drained.

Well I know things like interior lights, seat belts, key chime, clock and I can probably find most of them.
The challenge for me I guess is how to disconnect these things.
