Car alarm

Recommended Posts

Car alarm went off at 01:30 hours and wouldn't stop with the key, I had to disconnect the battery. Called the RAC and he couldn't solve the problem. My friend had the same problem with a Ford Galaxy, he changed the battery and the problem stopped. Later I charged the battery and the problem dissapeared so I took the car for a run. When I cot home and locked the car, the alarm started again so I had to disconnect the battery once more.

Has anyone else had the same problem, if so could you please tell me if and how you cured it. Thank you

Hi there, it sounds like the alarm is sensing a voltage drop in the electrical system, could be nothing more than a bad earth on the negative strap from the battery. How old is your motor?

Thank you for the reply. I thought of the drop in voltage, I checked the battery and charged it but after a few hours the alarm started again. As the car is 2006 I thought the battery was on the way out so I bought a new one but still the allarm went off. I took the car to a Jag specialist and he put the diagnostic on it and found the passenger door mechanism was at fault which was changed, there was also a problem with the ECU, that has now been sorted, at a price.

Thank you once again for your reply. Very bes wishes Tangaman
