    Hi guys, lovely day in Melbourne thought I'd do some work on the zed. So after the car was stolen, the interior lights stopped working. And I also noticed the central locking wasn't working. Took a look at the fuse today and it was blown, tried to replace it and it blew straight away. The car was off and so was accessories.

    As mentioned earlier the door ajar Light is faintly on. Probably the old bonnet switch wire shorting to ground but I can't find it. Is the bonnet wiring a factory thing or put in by an alarm installer? Can I disconnect it from the cabin since I can't see it in the engine bay?

    To rectify your problem, or any problem relating to an electrical circuit, you will require two (2) things.
    No.1 is an electrical circuit diagram.
    No.2 is a multimeter (preferably a high quality unit).

    I noticed another thing. There is a buzzing noise that comes on when the Interior light is set to ON and the driver's side door is closed (door switch held down) and the door is unlocked. When you lock the door it goes away. Passenger side door was closed and locked. The buzzing noise sounded like it was coming from the driver's side door.

    I also found a length conduit in the engine bay. I was prety sure this had 2 wires going to the siren, which has been removed. I peeled it back and noticed a 3rd blue wire that was cut a foot shorter than the red and black wire. Will investigate further .

    The alarm control unit was ripped out. A whole bunch of wires going to now where.

    Very difficult when these things happen, I've had a couple of them. Electrical shops/owners wire in after market alarm systems differently. I found the best way was get the car back to base design. So as ECZ said get yourself the original electrical circuit diagram and a multimeter. Remove/replace/relocate wiring as required to get system back as close as possible to standard. This is not easy.
