Broke down in the Land Rover dealership car park... in Australia. Not the best place, but got it recovered to somewhere who seem pretty good and do lots of British/Euro sports cars.

It was throwing up power supply errors, sometimes doors weren't opening on the button, sometimes it would do the start up procedure fine but when I press immobiliser to prime fuel pump it would die, sometimes I would hear lots of clicking but no turning over.

Was running fine until then, apart from dieing a few times after hot starts - which was odd.

Suspects:

1) Battery - possibly 6 years old, but always kept on Accumate (but was left for 3 months while shipped until arrival 1 month ago).
2) Battery connections - I recently put the cover back on it and it was pretty tight - so maybe something worked loose.
3) 100A fuse - but this was replaced for a 120A a few years back, so doubtful
4) General connections - looked in both footwells and nothing stood out but appreciate it's hard sometimes to spot a dead fuse.

I had been getting water temp sensor errors recently, but think this is unrelated.

1. Replace Battery...batteries are cheap and it's not worth to search for a problem when it will be in the end the battery

2. In the passenger footwell there's another 100A fuse, behind the vertial cover. Replace it ! This fuse can wear and then you have problems with current supply to all the important functions like ECUs, Dash Pod .....

The passenger footwell midi fuse was a bit bent, but looked/felt intact (I know it's hard to tell).

I'll wait to hear back from garage but battery/connectors was what I asked them to start with.

+1

Definitely get the battery replaced, this is the first thing I had done when mine landed in NZ and it's been absolutely spot on so far.

Replace the fuse with a better one anyway, even if you can't see anything. Will help you in the future ;-)

I should have really drawn up and imported an essential spares kit before I came over here!

Got people visiting at Xmas, might be worth getting throttle cable, various relays/fuses etc?

If you can get it started on jump leads or after a charge what is the voltage readout on dash?

Voltage readout was about 7v when I first looked, which went up to 11v when I plugged in another battery from the dealership via the Anderson connector - wasn't a running car though.

Assume trackers aren't standard also - found some black boxes while exploring with an antenna & GPS unit plugged in.

Might be worth getting removed at some point anyway.

Could do with knowing if the readout goes up when it's started. Should be 13v+ if the alternator is charging properly. 7v is very low no wonder nothing worked.

Starting involved the clocks resetting IIRC, forgotten now.

Sometimes one of the needles would sit halfway up the range from when it did the startup procedure.

7V sounds like nackered fuse or battery, they usually die when they get below around 10 or 11 volts as the ECUs can't cope with the low voltage.

A healthy battery should show about 13.5V / 13.6V - mine drops to about 12.9V on tick-over with everything turned on (fan on max, air con, stereo) then increases to 13.4 again when I start driving it.

I brought over a box of spare fuses, bulbs, servicing kit (air filter, oil filter, fuel filter, spark plugs), also brought in a pair of spare front discs and pads and an aluminium radiator but these were loaded in the boot of the car when it was shipped.

Sounds like a dead battery to me. 6 years is a good life in a normal car, never mind a TVR.

As is the battery accepting a full charge, or is it dropping?

Hopefully garage will sort out whatever needs doing.
