Having a few issues with the battery and noticed that the car when "switched off" still pulls half an amp out of the battery is this normal? On a 70 amp battery this give me only 140 hours worth of charge. Used it most days during the summer and not noticed it but having used it less over Xmas it's been flat almost every time I've gone to use it.
Check the ignition and the fuel pump relays in the foot well Black base and blue base, they should be the same. They some times stick or the diode has gone. Bosch 0332014112. If one of them feels hot when the car has been switched of for a couple of hours that is a sure sign that it is u/s.
Good luck Len.

I haven't measured the drain on mine, but a lot of people have had problems if their car is left for a couple of weeks, hence they use battery conditioner/trickle units(ie accumate etc.).
It has been suggested that the alarm can be bit of a drain; hopefully someone will be able to give you some actual figures.

Assuming you have a clamp tester of some description, or a way of measuring current, why not pull each fuse individually until you narrow down the area of concern, albeit not forgetting the alarm when armed?.
Anyone tried one of these?

There's a few models, this one has remote control which would be handy on our cars.

Try this one, if you can find it? Cheap and simple to fit. Just screws onto bat terminal. Can be used with or without 16 amp anti theft fuse. Ive had it as a spare 10+ years. The others are more tricky to fit and need a fabricated perspex clamp on the top rail in the 'black hole' footwell. Done this on my Griff.
Hi Angus,
I have been running the Battery Brain for now over a year and 1/2 and only had an empty battery once: the battery brain had failed after 10 - 11 months (and has been replace by the supplier).
My car is often not used for 2 - 3 weeks at the time.
I have the "gold one" (with remote control) and I think it is brilliant solution for anyone that does not use the car regularly enough or does not have power in it's garage (for use of a trickle charger - I do not have power in my garage).
Battery Brain is brilliant, get one and you will not be stranded anymore!!!!

You have to remember one thing ,once you disconnect your battery it invalidates your insurance ,thats why i use the Accumate ,plug in and forget ,keeps yor battery alive .

Disconnecting the battery is only curing the symptom of the fault, you need to correct the fault.http://www.ebay.co.uk/itm/Accumate-6v-12V-Motorcyc...
If there is no additional current drain other than the alarm (at correct amp) then the accumate will keep the battery topped up for extended periods of the car not being used, however, if this is only masking a fault then your fault may come back to bite you.

EGB says: Not if insured and in locked garage with keys removed. Mine is ok, have checked with my insurer. There are lots of other ways as well of imobilising, including the obvious. Cheers.

My car used to drain a battery in no time at all if it wasnt used weekly or left with the battery disconnected (I have one of those red key looking things under the dash) It ruined a new battery in no time at all!
All of the alarm relays where cleaned and not only did the central locking fix itself and the indicators stopped staying on at random, it also holds on to is volts for a month now! Pretty sluggish turning over after that long, but still enough keep everything alive.
It saved me a new alarm system as well.

Thanks TVR8 much appreciated, i can only assume its somehting to do with the alarm/imobil. My old battery was shorted at some point as well, so new battery gone in today and its sounded a lot better but that drain will still be there. Will check those relays next! but I assume they are under the dash board which only got put back in a few months ago........never planned to have it off again.... the joys of TVR ownership. Roll on Chatsworth in April, may have it sorted by then ;-)
