I own a 1997 Celica Convertible GT. After standing without use for a few days the battery discharges. I've checked most of the obvious culprits (i.e trunk lite switch failure, etc). Has anyone had this problem? It seems to be somewhat intermittent as sometimes it takes longer than other times to drain or doesn't drain at all. I hope its not a short somewhere in the wiring harnesses as there are probably miles of wiring and mostly buried.
