Parasitic power drain? 95 Park avenue

Seems like this is a separate issue than I thought it was when I started posting here: https://www.teambuick.com/forums/sho...329#post105329

It made it seem less difficult so I tried it.

Battery was at 13.06v when I began, 12.85 after tests and disconnecting
Attachment 726029ma draw so I pulled and inspected each fuse. 9D looks blown but has no effect on the meter. Fuse 9C, when removed, dropped the drain to 23ma. Nothing else effected the readout.

And,

Well that explains why nobody missed 9D. I wonder how to proceed from here. I kind of narrowed it down, I think. But, I only narrowed it down to a huge mess of wiring.

Also, maybe the radio's digital clock just pulls 6ma? It always stays on.

Even if the clock does pull 6ma normally, there's still something else drawing 23.
I did wait about 10 min before checking, after having hooked up the meter. Although I did open the door and set off that light. That draws much more but it goes out after a few seconds.

Is the next step to do the same with all the fuses and relays in the rest of the car? I see some on the right side and there's probably some under the hood. Thanks

Excellent test technique and results!

Attached is the Parasitic Draw Chart showing drain by device. 29 ma is a good reading. Battery should stay charged for weeks without being used if draw stays at this level.

Voltage readings look good too.

Wow. Hmm. So I guess it just drains the battery fairly quickly just having it hooked up for a few hours while tinkering with the passkey reset procedures.

One set of instructions did say to hook up a charger while doing the procedure. I did, last time, and it still left it half drained. Maybe I just need a newer charger. Hmm. Well thanks again TODD. My hero.
