Car alarm.
I've had a few false alarms on my car (96 z28), always in the wet and to date they have always cleared by locking/unlocking the doors (so turning the alarm on and off).
Today its having none of it. If I set the alarm with the key fob it waits 5 seconds and the horn starts beeping. I've unearthed the shock sensor and when I tap it, it has a little red LED which lights up. Closing up the car again, the horn still goes and the light on the sensor doesn't light - I guess that means its not the source of the false alarm.
Both doors and boot/trunk are shut - what else does the alarm monitor?
I just tried removing the shock sensor - just unplugged it from the wiring loom about 3 inches from the sensor. Seems to have cured the problem and the alarm still triggers on the boot opening unexpectedly. I guess this means its the sensor or the wiring loom?
Any help appreciated (by me and the neighbours!)
