A fault in the alarm wiring stranded me 300 miles from home, leading to the use of a relay recovery service, and took an auto electrician 2 hours to trace and another hour to remove the **** thing completely and chuck it into a bucket of water to stifle the sound cos it thought someone was attacking it (which, I suppose, was correct).
Ask LMG about Triumph fitted alarms - his kept going off in the middle of the night and he was extremely unchuffed about trying to remove it whilst partially undressed :lol:
I also hated the fact that it would arm itself whenever I turned the ignition off, which often led to fumbling about for the fob in motorcycle gloves.
