Hello and Welcome to justanswer..

My name is MIKE - Im happy to help you with this...

You have evidently been doing quite some work on this to find the fault tracing as you go....

Can I just ask - has the vehicle been jump started at all - and with the possibility of the jump leads having been incorrectly connected?

The van battery was flat and a booster/charger was conected to the battery and swithed on there was smoke from behind the glove box and the charger was switched off on inspection it was found the charger was on 24 volt setting idiots!

Hello again Brian -

Thank you for your reply and info..

Im sorry to hear that - You can see I had something similar in mind to what has happened ! Often times its a reverse polarity situation with the leads - but this can cause equal damage.

Now - Im going to run through it all - even though you have now done some repairs -

What you need to do now Brian is make a physical / visual check to trace where this smoke is coming from -

Its common to get the ignition electrical unit - on the end of the ignition under the cowl behind the steering wheel to burn out - so there's that... Also -if the smoke is emanating from deeper in the dash, there is every chance the wiring has fried / melted... Basically you are going to have to strip as you need to find what's happened -and then hopefully you will be able to repair it.

I have to say its not unheard of for such to write a vehicle off ... wires -the whole loom either in the engine bay or under the dash up through the fuse boxes etc to the ignition can melt instantly under these circumstances - too rapidly to stop it while connected to the charger (or whatever the cause as above )... Too of course, it can take out the 12v Ecu's / computers -

I now note you have now done some wiring repairs - if it still wont go -you need to check the fuse / relay boxes - especially the underside for damaged wiring etc - and melted contacts.

IF all that is ok - then yes - you are looking at Ecu etc - A plug in diagnostic would be the next move now then - before sending anything off to ID exactly which module is not registering etc.
So at the moment its a search and find job Brian .... and then go from there, as you find. Let me know how you get on- Im always happy to help as / if needed more so -

Let me know if you need anything more on this at all -
