Hello
1993 L reg SPI Cooper
Context
I am an idiot
Background
Air filter box, throttle body and inlet manifold removed
Inlet manifold expertly refurbished by Roger Carpenter (Mini Forum member and all round good guy)
All sorts of things disconnected, lying loose and dangling
Including the pull cable that runs across the top of the air filter to the heater valve
The cable with the circular wire end that hooks onto and pushes / pulls the heater valve
Enter Stupidity, Stage Left
On receipt of the returned, truly wonderful inlet manifold and in unbridled desperation to get the thing reassembled and the engine turning over, I clipped the maintenance charger onto the battery terminals for a top up while I was working.
Car battery terminals also still connected
The bare metal circular metal end of the pull wire that goes to the heater valve was tucked out of the way while I reassembled things
It must have pinged free from its wedged location
The bare metal end made contact with the engine block (I think)
Arcing, fizzing, unpleasant words and some panic
I whipped it away after about a nano second
I disconnected the maintenance charger and the car battery terminals and carried on
A few days later, I reconnected the battery and turned the key
Nothing
Not a click or a buzz at the starter motor
Next Steps
I changed all fuses
It cost less than a tenner so I thought, why not?
I disconnected the battery and charged with a normal battery charger
I reconnected the battery to the car terminals
Turned the key
Nothing
Not a click or a buzz at the starter motor
Immobiliser
I have an immobiliser
It usually has a flashing red light on the dash
I usually hold a "thing" to a "receiving thing" for a few seconds, the light goes off and I have 30 seconds to turn the key and start the car
I'm sure you know the type
I currently have no flashing red light
I'm assuming the immobiliser was affected by the arcing / fizzing event, but is there more to it than that?
When I've had a failed immobiliser in the past, there's still been power, the starter motor still had a go, but now, this time, nothing fires
It is just all dead
Other info
Fuses
I changed the 4 glass fuses in the Lucas fuse box in the engine bay
A previous owner must have changed the inline fuses and inline fuse carriers for a bank of blade fuses
So I changed all of those too
Before this, everything was fine
No electrical issues at all
None
Any ideas?
In eejit friendly plain English (as you'll have gathered, I'm no mechanical or electrical genius)
Is there another fuse / set of fuses somewhere else?
Thanks in advance you wonderful people
Regards
