battery kill switch

    well everybody.
    i'm looking to add some extra security and have gotten myself a battery kill switch. Im handy with the spanners and all that but i'm wondering if this is the case; there are three wires connected to the positive terminal and likewise three on the negative. One wire on each side of the battery is heavy duty and then there is a couple of smaller earth cables and positive cables that were put in for fogs. Is it just a matter of redirecting all these wires to the killswitch so i'd have 3 on the positive side of the switch and 3 on the negative? I know i've gotta put an line fuse somewhere too but that was my main query. Thanks in advance.:D

    What exactly are you looking to do with a kill switch? Disconnecting the live or the neg from the car won't stop it from running.

    AFAIK it's a button that one would hide somewhere and can turn it on and off, without a battery the car obviously won't start :P

    Yes thanks, I'm aware of my understanding of of a kill switch. However you're use for it is pointless. The car can still be started, and once started can stay running. The reason I asked the OP this question is because I got the impression they have the same thinking as you, when there are better ways. You can have the kill switch on the ignition circuit, and when its engaged the car either won't start (but will turn over, thus creating noise) and if the car is running it will automatically kill the engine - hence kill switch. If its done right, and inconspicuous enough then it would be the most effective anti theft method available.

    Use a kill switch for power to the fuel pump instead OP?
    A battery killswitch would be a pain in many cars since the late 90's, and almost everything from 02 on - your ECU would constantly be in "learning mode" (lower mpg). And you'd lose all your radio stations, and possibly be plagued with entering security codes, depending on the radio. You'd lose central locking and remote locking.

    If the car only saw very infrequent use it might be handy alright, but at that rate you'd be as well to just disconnect the terminals until you needed it next.

    thanks for the input lads. I was thinking about the fuel pump option alright. Might be an easier road to go down.

    As said, a battery kill switch on a modern car could be a nightmare.

    A kill switch for the fuel pump is much harder to get around.

    What car is it?

    I have a Carina E that has a kill switch, it was fitted before I got the car. When you flick the switch and turn the ignition nothing happens. All the lights come on the dash so it must not be cutting the battery. I haven't ever had a look but would it be possible the switch is on the starter motor?

    If the igniton comes on and it doesn't turn over it probably causes a break in the wire going to the starter solenoid.

    Effective but easily got around with a coin at the starter. Cutting the power to the pump is harder for tea leaves if they want to take your car
