My dads power sounder keeps going off randomly.

its done this ever since i sent a pheasant to meet its maker.

It hit the bumper and broke the bottom bracket for the headlight.

any ideas what would cause this?  have since disconnected it and its making life easier on the ears (and the neighbours!)

Hi
An obvious one to check is that the bonnet is shutting properly, if not the alarm button under the bonnet could be triggering the alarm.

Hope this helps
