I haven't seen anything on at all - no brake lights, nothing at all.
Will be testing as much as I can this weekend with my multimeter - thanks for the reminder re: letting the car sit for 45 minutes to ensure everything is powered down.
What do you think of the battery picture - the droplets & obvious dried accumulation on top?
On the way home from work this afternoon I'm going to stop by Wal-Mart and buy a new battery anyway. I don't like the droplets I see on top of the existing battery and as I said way up in an earlier post when these shenanigans started, it won't go past 90% on the charger. I just don't trust it.
