That looks to be perfect for what I had in mind, Many thanks.

Just a warning shot if you have a TVR with a 14CUX ECU fitted, it needs to be connected to the battery all the time to remember its fuel trim settings. If you disconnect it has to re-lean them again at idle on a hot engine, and it takes around 2 mins. The car will still run after a power disconnect, but not so well until it gets itself sorted again.

A personal recommendation is always good, thanks for that.
Did you go for the Engine Run wire or the Vibration Sensor? Looks fairly easy to install, any problems?
I bought mine with the "engine on" wire, it is quite straight forward if you follow this. The hardest part for me, was finding a wire on with ign only. Oh one last thing, I managed to snap the battery terminal provided, it broke as I pushed it on the + terminal ??!! So buy one before you start or be very careful .HTHDid you go for the Engine Run wire or the Vibration Sensor? Looks fairly easy to install, any problems?

I was wondering where you would find an ignition live feed too. Someone at work suggested the Fuel Gauge positive lead. Should be ignition live, but would it affect the fuel gauge reading in some way?Bob
Hi guys. I am from BatteryBrain in the UK and would like to advise that the engine on wire is being phased out. The current Type 3 BatteryBrain's will come with the ERD (engine running detection) function built in. This monitors the "electronic noise" created when the engine is running therefore eradicating the need for either the vibration sensor or the engine on wire. This will make installation even faster and simpler. We have just launched a new website so installation links are now here - http://www.batterybrain.co.uk/support/
Also further information regarding the ERD and engine on wire are available here http://www.batterybrain.co.uk/faq/

Battery Brain Type 3 Gold 12V Manual Reset, Dual Remote + Anti Thef
in August last year but its only just been fitted. Can I assume that it will have the 'engine on' cable.
By the way, I had one fitted to my previous Tuscan and I thought it was great.
Pity I wrote that car off a few months later.
I fitted the Battery Brain (Gold model with IR remote) to my Chimaera over four years ago.
It's uniquely useful feature for TVR owners is its the only remote battery isolator that I know of you can easily switch on and off with the car completely locked, I just lock the car so its secure then hit the Battery Brain remote to disconnect the battery.
I hear the little click and see the flashing alarm LED tell tale go out, which confirms the battery is disconnected. The car is now deadlocked, the only way to get back in is to press the Battery Brain fob at which point the indicators flash to indicate the battery is reconnected. Then and only then can you use the TVR alarm fob to unlock the car as normal, this works great and has proved itself to be totally reliable over a number of years, just don't drop the Battery Brain remote on a hard floor (more on that later).
With the Battery Brain activated a fit & healthy battery will still have sufficient charge to start the car six months after the day you last drove it, and no trickle charger required which makes it ideal for those without mains power where their car is stored.
The only negatives are:
1. You need to accept there is still a tiny parasitic drain because the Battery Brain remains live as it always needs to be ready to receive the "reconnect" signal from the remote fob
2. The remote fobs aren't very robust, I dropped mine and it died, saying that this was the old fob design which has now changed and you do get two fobs with every kit
3. The post extender terminal in the kit is made from very poor cast monkey metal so if you over tighten it just a touch it will fracture, I purchased a proper tinned brass one from KoJayCat which is much much better quality than the cheaply made one you get in the Battery Brain kit

Personally I see a Battery Brain Gold as an essential accessory for anyone who has a car with central locking that they use infrequently, being able to disconnect the battery easily after the car has been locked is a brilliant feature.
I've had no issues with my alarm activating when I reconnect the battery, my radio presets are also retained as I've wired my head unit to one of the two permanent live accessory terminals provided on the Battery Brain device.
Battery Brain Gold - Not 100% Perfect (see negatives) - But Highly Recommend!

Hi Guys,
I had my battery brain fitted for 5 years.
My card often stays un-used / un-started for a couple of month at the time, sometimes more (in a garage without power) and the only time it had not started was after I had my car serviced and the battery brain had been badly connected after a battery change.
I took the car out last Thursday for the first time since 31-12, this is over 11 weeks and she started first thing, as if she had started the night before…
The battery was low as each time I activated the battery brain, it shut itself off within a few seconds, but got the car started, took the car to work on Thursday and had her all day on the trickle charge and used her on Friday, Saturday & Sunday without any issue.
Not only battery brain allowed me to start my car, but also saved my battery to go completely flat and probably in the process saved my battery from being damaged.
Battery brain is amazing, I would recommend it to anyone that has a car that is not used often and does not have access to power to run a trickle charger…
As Dave / Chimponegas said, the bleepers and connectors are not the best in the world, but they are adequate and the product is actually fairly cheap…. And above else, it works!
