When diagnosing a battery that discharges, check for current draw. The interior lights ground connection could contact the positive lead. This activates the power window motor relay and discharges the battery in a relatively short time.

From production date end of May 1987 the body ground connection is bent to the side and additionally insulated.

To repair cars prior to the above production date, bend the ground connection to obtain the necessary clearance and insulate it.
