    Alarm sounder

    Sounder has gone quiet, investigating I have found both fuses, 5a and 30a, in the engine bay box have blown. Anyone has similar, I haven't tried replacing them yet but there must be a reason that they have blown?

    Usual reason is water damage in the sounder unit. Either disconnect the sounder and ignore or replace/fix the sounder unit. It contains batteries that can also fail and damage the unit.

    When did it ever sound? I've never heard mine despite replacing the re-chargeable cells, but then isn't it only meant to sound (in UK) in extreme circumstances, such as disconnecting the main battery while the alarm is set?

    It used to chirp when locking the car.

    Interesting. My handbook says

    Alarms and audible signals
    Note: In certain markets, legislation
    prohibits the use of alarms and audible
    signals. In such cases, the sound source
    has been removed from the system.
    Legislation requires that the
    United Kingdom, European and
    Middle East markets no longer have the
    audible sounds when arming and
    disarming the vehicle.

    so I wondered if yours sounded at some other time. Anyway, no mystery after all! Don't the neighbours moan when it happens at 2 am?

    Mine’s a 1998 convertible and it chirps on locking and unlocking. Not loud enough to annoy anybody though!

    It is a programmable feature that can be switched on or off through the OBD port. When I had my XK8 I had it switched on by Jon Greive at Jagcare in Pompey, though your above is also true.
