2009 EX-L with 38,000 miles on it (of course just passed 36k in last month)
As reported by my wife:
"Pulled up to Chick-Fil-a drive through window when all of sudden there was this loud noise from under the car. Loud bang and hissing sound, followed by nasty burning smell. Immediately parked the car and got out, turned off car."
After inspecting for leaks, fire, smoke, found nothing. Started car and observed no problems, drove car home (about 5 miles) and parked it. No idiot light or other problem. A/C is working as are all other driving systems.
Let car sit overnight and the battery was drained such that car would not start (got that clicking sound only) There was enough power to operate the power doors. Disconnected positive battery terminal and charged battery overnight. Battery drew over 8 amps initially but tapered down to zero after overnight charge (seems normal). I'm hoping this is fairly straight forward since there is clearly a short circuit somewhere which should lead me to the problem.
Luckily I just bought the service manual and electrical troubleshooting manual from someone on ebay. So I imagine if I start pulling out fuses in a logical sequence and monitoring the battery drain I should be able to narrow this down. For starters it is something that is in the "always on" circuit path, not switched by the ignition.
Any tips or tricks are appreciated. I wish I had one of those clamp on ammeters, i only have a cheap-o in line VOM ammeter which probably may not handle the current draw.
Thanks,
George
