I have a battery drain of about 0.06 amps which is sligthly above the 0.02 amps "spec". I know this is not a lot, but the battery does drain significantly more quickly than other C5s I have owned. If a "normal car" drains the battery to a no start condition in 30 days, my will last only about 10 and I notice lower voltage after about 7 days. I have a brand new battery because this drain slowly killed my other one. I also keep the car in reverse.

I have completed the obvious items and checked:
Seat
Alternator
Bose
RAPP

I also traced this to IGN fuse #1 per this post.

When I remove IGN fuse #1 it drops to 0.02A. I also pulled all fuses shown in this post including branch "F" and it stays at 0.06A

Is 0.06 amps still the best I can do? If not where do I go from here?

The link is now working.

No info in your sig, so I have no idea what year you have.

I thought you had me for a second. The fuse you are talking about, is fuse #45(for a 97-98) or fuse #47(for a 99-04) NOT fuse #1. Specifically designated: "IGN 1, fuse #45 or #47)".

When the ignition switch is in the off position, there should be no current flow.......so pulling fuses downstream is kind of pointless.

You likely have a defective ignition switch which has a leakage current path on that circuit with the current tracking through the switch to one of the circuits powered by the switch. Try unplugging the ignition switch to see if the current drain drops back to 0.02A.

The leakage path could also be in the fuse block and, least likely, in the wiring itself.

It is a 2002. I removed the ignition switch and still have 0.06A after 15 minutes. However, when I remove the IGN #1 (which is fuse 47) I once again get down to 0.02A.

Any thoughts on where to go from here?

That leads me to believe, that a previous owner has tapped into that circuit to the ignition switch. Can you trace the wiring from the ignition switch connector, and see if there are any splices?

lionelhutz

You need to examine the wire and other parts (fuse block, ign sw plug) between the fuse and the ignition switch.

Vicarious.

would a bad ground wire cause this?

pelensky

You were spot sir! I traced the ignition wires and found a splice that lead to an aftermarket module that had a coiled up wire (maybe an antennae). My guess is that it was a lojack. I disconnected it and the battery drain dropped to 0.02A.

So for future knowledge it looks like a lojack (if that is what it was) is worth about 0.04A and will reduce battery reserve to about 10 days or slightly more.

Well done
