Further to an earlier post, my alarm is still going off,
What I have tried so far;
removed power sounder, pressed button inside car with man walking away, removed bonnet switch.
It still is going off every 4 hours or so, It's driving me mad, only way to stop it is leaving locks undone, can't do that where I live.
Manual is at work, spent half an hour on here trying to get some help but search is not coming up.
Anyone know if there is a simple fuse I can disconnect to stop alarm before the neighbours start knocking on the door
cheers Pete

As you've removed bonnet switch try shorting out the two terminals the switch connects to - this worked for me on a Rover with a faulty bonnet switch.
HTH :y

Not a fix mate but, when you get out the car,open the rear door and reach through an push the drivers button down. ENSURE you have your keys and shut the back door,car is locked without the alarm being activated.........
At least its locked and the alarm should not go off
-
Is it the horn thats sounding now if you have removed the sounder?
-

Hi yes the horn and the hazards still going. Have locked it as you suggested, I assume this definately does not arm the alarm? as when you lock it with the key it does.
Thanks for the help, 2 hours of peace so far and the wife is looking happier!
-
Yes mate the alarm is armed by the key.....i had the same problem with my power sounder for a couple of days,i used the back door locking method and it kept it quiet
You need to get the bonnet switch fixed,i would say that it has an open circut making the alarm think the bonnet has been tampered/opened........
Why did you disconnect it?

Sounds stupid mate,but its been known before for a spider to be crawling around inside the car in front of the sensors,even though you said you have switched them off,are you sure they were off properly?otherwise is there damp in the system,you will be surprised what damp can do. :y
-
Yeah agreed,but still think the lack of bonnet switch is the problem
-
removed switch as I was systematically checking each component, the booting around the spring has cracked but multimeter says it's fine, I guess damp could be the problem then, as this only started on nights below zero, although it does go off round the clock, it's favorite time is 1-3am!
-
Well,WD40 all parts
Test for the bonnet switch would be,open bonnet.....hold pin switch down with finger....set the alarm (30 secs) let the switch go!
If alarm goes off its working,an may just be bent slightly
You should get a quiet night by locking it the way you have....

Sods law pete. ;)

I wouldn't use wd40 on electrical contacts as it will short contacts out. use a contact cleaner like servisol super 10 from places like maplins about £4.29 for a spray can. This will clean & lubricate contacts. :y

Hi I did all that a few days ago, even methodically checked the allignment of the plunger with bonnet.
Never had WD40 short out circuits in the 20 years I have been using it!
-
wd40 is well known to drive out moisture,and also a very good upholstry cleaner and stain remover. :y
-
I have, but you can get away with it. I think the contact cleaner is the best way to go.
I'm sure people will put me right on here though ::)
-
It's been a good friend over the years!

HTH :y
Shorting out the 2 terminals will NOT work as that is the same (electrically) as the bonnet being open. If the switch is removed/disconnected then that's the same (electrically) as the bonnet remaining shut
-
Well so far power sounder is disconnected, bonnet switch is disconnected and have tried the internal sensors turn off method, alarm still sounding so have been locking car as per Iain's method which has given us 24hours of peace and I'm back in the good books with the wife!
Will clean all door switches again soon and try then
-
At least it has shut up mate,give you peace til you can figure the problem
-
Hi i have the same problem with my omega 2.2 auto when i lock my door as soon as the flashes get slower and i open it again the alarm goes off the only way i can stop it is by putting the key in the ignition any ideas?
-
Is it an estate? Check rear window breakage sensors.
Failing that, how far is it to Hotel21, who has a code reader capable of interoogating alarm ecu to find why its going off.
-
Hi ya.
This sounds like a problem I had. Even had the alram going off when I as driving once or twice. I did get a solution so you might like to try this.
The alarm in mine has a siren and a horn buried under the scuttle panel on the offside. If you take it out you will see a large block shaped thing comes with it. This contains, among other things. a couple of AA rechargable batteries. Over time these degrade and become unreliable with the result that the charge when the car is running but the charge drains out quite quickly thereafter. Once the charge drops below a trigger level the alarm system senses it and triggers the alarm. A temporary solution is to remove the whole unit. Certainly cured the problem with mine
Hope you get a solution.
