I have a 2000 306 XSi 2.0 with a very annoying alarm. Most of the time
after it has rained, the car alarm will trigger if the car is locked
or locked and alarmed. The only way to stop the alarm is to
disconnect and reconnect the battery.

Has anyone ever had this problem happen with them and if so, what if
anything was done to resolve the issue?

Does anyone know which fuse controls the alarm as the owners handbook
doesn't seem to match my car when it comes to the fusebox?

Appreciate any info anyone can give me!

Cheers
