Hmmm, haven't run the LS in a couple of weeks, go to show it off last night to some guests and the darn battery was drained down somehow.
I do have the trunk off but I had disconnected the trunk switch by it's connector so the lights wouldn't stay on. Not sure why this LS is so subjective to battery drainage within 2 weeks. New battery as of last year. Last time it did this I had left the interior light switch on. That wasn't the case this time.
This known battery drain on the LS is rather irritating. You'd think you could leave a car sitting for a couple of weeks and not have your battery run down.
