I have one of the old conciept 50 alarms on my motor and all was well till today when a jack folded causing the front of the car to hit the ground! No damage was done but the alarm went mental and would not turn off! I ended up removing the batt connection to silence it.. When i sorted the car and refitted the batterie i opened the car and drove off! As soon as the car was in motion the alarm started chirping and the interior light was flashing! when i came to a stop the car died and now refusses to start or function the ignition.. Any ideas to whats happened here guys??? Im thinking it some kinda impact sensor protection! Cheers rich
