Hi
I have a ST170 and the car alarm keeps going off i have bridged the bonnet switch but the bugger keeps going off!!! It normally starts going off in the afternoon about 2ish then can go off 7 times within the space of 20mins!
Please need some much needed advise i havent had the car long and its doing my nut in!!
Cheers

 

What alarm ?, is it a std ford fit one ?, does it not have LED reporting to let you know which area has triggered ?

its only a std no it doesnt have led its a 52 plate car
cheers

 

Interior light stuck on somewhere? Like in the boot? As I remember the battery saver could kick off the alarm if a light was on due to the load change.

Or possibly volumetric triggered as the car warms up in the day? Have an idea this could be from the boot vents not working correctly.

Though it's a long time since I had one so not 100% sure - got through 3 of the things so I saw most things at one time or another.

 

I had the exact same thing on my ST170, i bridged the bonnet switch and it stopped going off so got a new switch, if its not the bonnet do the same on the door and boot switches till you find out which one is faulty then replace it
If it is neither of these then disconnet the interior sensors located either side of the interior light

 

Hi right it has got to be the boot do u have to bypass or just un plug?

 

Unplug the sensor and as a temporary measure stick a wire between the plug connector to create a complete circuit. This will fool the alarm into thinking the boot is shut, i feel you pain mine used to wait till 3 or 4 in the morning before it started going off constantly, so i used to leave it unlocked but this meant dragging my ass out of bed and having to go out there and atleast open a door or it arms itself again
