just got a 97 spyder, everything works fine, except for alarm.
if I push 'door lock' button before leaving the car, the green security light goes on for a few seconds then goes off, then the anti-theft system start to work, it's still ok.

but during the night, the alarm got triggered intermittently, sometimes 3 minutes after lock, sometimes half an hr, sometimes a few hours, it is really irritating and nobody touches my car, not even a squarrel.

I tried to pull off the fuse for anti-theft in the fuse box but the alarm still goes on some times.

any trick?
