    OK, did buy a new battery last week, was being very lazy and not spending time with my baby..... (My Car)..... Anyway woke up this morning battery dead (WHAT THE **** man I should of tested it before spending money on a new battery)

    So I take the day of work just to spend some quality time with my baby to see what the problem is, cant do much because I'm in south, and my tools are in east...

    So any how, got a multimeter from someone, but it does not read A, oh it reads mA, but i'm sure you can not run any tests with this.....



    Any way just want to make sure a couple of things are normal....

    *when opening and closing door, this takes a lot of current
    (Hinged window, when pressing up it sucks quite a bit) (Interior lights, central locking)
    *Putting key in position 1 also sucks a lot of current


    Heeeelp pls

    Try the following http://www.wikihow.com/Find-a-Parasitic-Battery-Drain


    I would suspect a faulty final stage resistor though......as this seems to be a common one

    FYI final stage resistor and hedgehog are the same thing...

    OP if you follow the steps in the guide I posted up you should be able to localise the fault...it could also be door switches,boot/bonnet switches ase these are common too as is broken loom going into the bootlid.....

    Good luck...just a query you did buy the correct battery for your car?also do you have a tracker fitted as these can sometimes cause excessive battery drain too

    yea... gonna get both batteries tested 2morrow and see how it goes from there...
    No tracker fitted..

    Think it might be a switch doe.. (when closing door, turning interior lights on, starting car in position one) this sucks up a lot of current....

    wanted to know if this was normal.....

    thx
