Central Locking

<< < (2/2)

petergalileo:
Try locking and unlocking it with the key for a couple of days.  If it behaves itself with the key you know the alarm is the problem.  

The system on the series 1 disco works through an orange and a pink wire.  The current is reversed to lock and unlock.  for example orange positive pink negative would lock it, orange negative pink positive would unlock it.

You could trace the wires from the alarm to these orange and pink wires and test them with a multimeter.   I am not familiar with the laserline alarm but you might find the central locking system part of it runs from the alarm to a relay then to the central locking wires, if so check the relay too.

--- Quote from: "sharpshooter" ---Hi All. I have a problem with the central locking on SWMBO's Disco

Its a 200Tdi on a J plate.

It has an aftermarket LASERLINE alarm fitted, which also has taken control of the locks.

Disconnect the alarm from the locks, nothing but trouble and with a sniffer/transmitter the scrotes can capture the code, wait for you to walk away and unlock as well as disarm the alarm.

Add to that the MOD's use of 433.920 Mhz jammers (lots of reasons, all legal, its THEIR frequency band) causing problems with alarm remotes (new renal's without keys only fobs it means locked out if they switch one on nearby).... :wink:

I'd go with the stiff linkage but before you start ripping door cards off try and make life easy. Just sit and pull the drivers door button up and down lots and lots of times, it may just clear some much out and what have you got to loose with it?
