She's has a 1994 325i convertible and I can't make out if the alarm is working. The red alarm indicator does nothing. But if I put a meter on it, (ohms) it glows red. I should say this is at the base of the switch/box which fits in the console. I also know there's power going from the plug to the box.
I did try to trick the alarm by lifting the bonnet, then placing a brick on the bonnet switch. Then I locked to door, waited (no red light on console) waited and, waited. I removed the brick indicator lights flashed. no sound, and no red light.... still. Where's the sound???

The computer display has gone south, so I cant tell if it says anything, do you think it would? Would a scanner tell me anything?
Many Thanks Phil
