Possibly the little light in the back of the hatch is stuck on or something of that nature?

Hi Mr Windsor, welcome to SaabCentral.

A few things to try:

1) Disconnect one of the battery terminals before you go in at night. If the battery is still dead in the morning, you need a new battery.

If the batttery is OK:
2) Check the ignition switch is fully off. If it's not; the light in the main light switch will be on, anything in the accessories circuit will be supplied with current (if switched on), anything plugged into your cigarette lighter will draw power.

3) Check the quiescent current draw of any alarm or radio fitted.

4) Check the earthing points are in good condition (strange things happen with bad earths)

5) Check the battery is being properly charged. With the engine running the voltage across the battery should be 13.8 to 14.1 volts. With the engine off a fully charged battery should be more than 12.6 volts.

Best of luck
