She will not start.

OK - I'm having battery problems. Got in the car yesterday and the battery was flat. No problem I thought, just use some jump leads. So, connected them up, turned the key (engine running on donar car), TVR turns over a couple of times, but then stops and the electric mirrors start some sort of test sequence (which freeked me out at first). After that I have to remove the keys, insert the imobilizer jobby and start again.

Any ideas?

Cheers.

Time to fit a new battery.
Like Lambda sensors, dizzy caps, coils, alternators etc, on a TVR these are seen as consumables and, in time, have to be replaced.

Once a battery has lost enough charge to fail to turn over the engine it will rarely recover- no matter how long you put a charger on it. Try to buy an 072 battery with a three year warranty.

Okey dokey. How much is a battery?

Hello

On this subject of flat batteries does anyone have any recommendations of a good conditioner or had an experience of a bad one?
Just been looking on ebay and CTEK XS3600 120Ah Battery Charger and Conditioner looks quite good.

Thanks

Eurocar parts are quite good for consumables like batteries. There is one in Swindon in Rushy Platt and they are online.

If you're trying to jump start a car that has a flat battery, it's a good idea to leave it for five minutes or so with the donor car connected up (engine running) so it can put some charge into the 'flat' battery. That was you have one strong and one weak battery trying to start it, rather than one strong battery trying to fast charge a flat battery and start the engine at the same time.

I tried that - but no joy. What I can't understand is the behaviour i.e. engine turns for a few seconds and then nothing. Turning the key a second time does nothing until I reset the imobilizer. Why would that be?

Don't know, but possibly the battery voltage is dropping far enough to upset the immobiliser which is then re-arming itself?
