my motorhome is fitted with a sigma AC111 alarm which has a habit of going off for no apparent reason.I was told to allow the alarm to go off and run its course then switch of on fob, switch on ignition and count the warning light flashes on dash,it flashed 14 times.I was told this was the bonnet switch which I disconected but it has gon off again and still flashes 14 times.Any help woluld be appreciated.
