After thinking how trouble free my Tuscan 2 S has been for the summer it's thrown a wobbly on the way home. It was absolutely fine for 200 odd miles this weekend, I came home turned it off to open the garage and then when I re-started it and moved it inside it brought up a series of faults.

N.B. This is "Mk 3" so it has a WAVY dash the same as the convertibles.

First the lights on buzzer kept sounding even though the lights weren't on. I went in to the dash menu and cleared:

Fault 16 - Lights on Fault.
Fault 145 - F-RAM Failed
Fault 149 - Clock Failed

And now it has Fault 0 - NO Faults

WTF!! The Fault code is NO Faults!! I know we are to expect a few problems but a fault code for not having any!

Anyway the dash is all lit up and it sounds like something is running behind the dash. I have pulled all the relays and it has not turned it off. Now it is on an optimate but I can feel it getting very hot and I don't want to either have the battery get drained or worse still to burn something out or overheat or catch fire.

I have done some reading and it appears this may be the alternator causing the problem, but this is not my main concern. The problem I need help with is how to power it down. I've read about the "100 amp fuse" is this the main power fuses? Can this be pulled to kill all power coming from the battery? If so where is it as I had read it is in the passenger footwell but I couldn't find it at all.

So in a nutshell, the car is in a locked garage so I;m not waorried about the alarm but HOW DO I KILL ALL POWER COMING FROM THE BATTERY TO MAKE THE CAR SAFE OVERNIGHT?

Thanks everyone.

I've tried pulling all the relays with no joy.
I've tried turning the lights on and off with no joy.
Anyone know which is the fuse to pull but I think it may be more than that. It sounds like there is something running in the background.

OK.
Thanks to all that helped.

I managed to get the battery cover off without jacking up the car and taking the wheel off, it's a bit of a pain and getting covered in muck. I unplugged the battery and then re-connected it and that seemed to cure the problem.

One thing - Should the 100 AMP fuse be in the battery compartment?? That's where mine was so no wonder I couldn't find it in the passenger footwell.

I'm guessing the alternator might bu on the way out then???
