Don't know what happened this morning, was about to go out shopping valentine's day had suddenly become very important!!!. Wife was working so left with junior. Loaded him into child seat wonderful fun in the 2 door soft top, jumped into the drivers seat and nothing no ignition light no clock no interior light dead. Bugger must have a flat battery so popped on fast charge, got small one out of car went for walk. Came back 3/4hr later still completely dead. Decided to give up have a think and wait a bit longer, but also there's only so much "Daddy Car Go" from a 2 year old one can take.

The car is fitted with a aftermarket selca alarm although can't arm the thing, only had one fob which ended it's life in the fast lane of a duel carriageway after a short trip on the top of my wife's car about 18 months ago. I have had no probes with it not working.
Unfortunately Selca are no more are in business but have the wiring diagram pin outs colours and connections. I looked at them and decided that the alarm could only immobilize ignition, fuel, or starter and not the whole electrical system but I may be wrong.

So whilst my son was stuffing down a chicken sandwich I quickly snuck out and put a meter on the battery 13.79v tried the key nothing and no volt drop, conclusion it must be immobilised somehow.

Finally I was able to get back to the car when small one fell asleep.
Pulled the panel off below the steering column identified the alarm wiring loom found the supply fuse, pulled that, alarm went berserk, put that back in. Disconnected battery pulled alarm fuse waited put battery back on put fuse back in turned key and guess what it started on the button. Did some wire tracing found all bar the two wires which immobilise the car. They are not connected to anything under the dash like you would imagine, so they must be in the engine bay.
So couple of questions

does the GV have a as fitted immobiliser?
what could possible be connected to the alarm in the engine bay to completely isolate to electrics on the GV :er:

The GV has a built in immobiliser, you will get a flashing immobiliser light if its immobilised. Do the two wires go to a siren under the bonnet? It sounds more like a bad battery connection.

No believe or not the siren is also the brain so a large loom comes from their. Did think possibly bad earth struggling though that have had no issue untill today
