- Battery Installation Check: First, ensure that the new battery is installed correctly. A wrong installation can lead to various electrical issues, including alarm malfunctions. Inspect the battery cables to confirm they're clean and tightly connected.
- Hood Switch: Sometimes, the hood switch can be accidentally bent or displaced during battery installation. This switch is crucial for the alarm system as it detects if the hood is opened. Check if it's properly aligned and functioning.
- Loose Connections: A loose connection, especially around the battery posts, can cause intermittent electrical issues. Carefully examine the area for any loose or hanging wires and tighten any that seem out of place.
- Alarm System Fuse: Consider replacing the fuse for the alarm system. A faulty fuse might cause erratic behavior in the alarm system. This is a simple and inexpensive step that can sometimes resolve the issue.
- Sensors and Wiring Issues: Late 90s luxury cars often have complex sensor systems. A dislodged or malfunctioning sensor, possibly triggered by the battery change, might be setting off the alarm. This may require a more detailed inspection by a professional.
- Temporary Solution: If the alarm continues to act up and you're storing the car under a cover, you might consider leaving the doors unlocked temporarily. This can prevent the alarm from arming itself, though it's not a long-term fix.
