Citroen Xantia Alarm Problem When Disconnecting Battery Negative!

[Guest Xantia_Dude]

Hi!

 

I need to disconnect the battery negative lead on my 1.9TD 1994 Citroen Xantia SX in order to carry out some work on it. I have disabled the alarm with the key under the bonnet and everytime I disconnect the battery, the alarm sounds! The alarm is very quiet even when I reconnect the battery, however when I switch the alarm back to the "on" position with the key thing under the bonnet, it goes to FULL volume(im guessing this shows that the alarm key switch works :rolleyes: ). Whilst the alarm is sounding very quietly and making strange noises, I have to lock and unlock the car with the remote and then turn the alarm key switch to the "on" position which gives a very loud "chirp", in order to get it to shut up.

 

PLEASE PLEASE help me if you can as I am unable to disconnect the negative lead!

 

THANKS in advance!

 

 

 

*UPDATE*

 

OK, now it trigger as it should, but i cant get the damn thing to shut up even when following all the correct procedures such as the remote, and ignition and switch thing!!

 

Please help
