1996 Alarm led being odd.

Upto very recently the alarm led on the dash board behaved just as it should, ie flashing when armed and out went not and so on. But now it just seems to be constantly lit, central locking, immobiliser etc work ok still.....
is it a sign of worse to come or can i just go on ignoring it ??

Ooooo, even light when driving? the signal to tell the immobiliser to set comes starts with the door pin switch it has severial uses such as used for the interior lights I would look at that first, second, fuse, third, I haven't a clue at the moment have you been doing any electrical mods on the disco.

yes even lit when driving ! interior lights all work from all the doors. Will go and pull a few fuses and check them now.

all doors (and bonnet) switches work perfectly, and all fuses intact and working, immobiliser works and indicators flash when a door is manually opened and then try and start it, turn off the alarm/immobiliser and she fires straight up. All through this the LED is constantly on. ideas , cos i have none !?
