Wiring a Kill Switch

    I have an old Toyota hilux, got new batteries last year for it but batteries started failing after a few months.
    It seems something is draining them as it is charging ok and the batteries have been tested and are fine.
    It doesn't get much of a driving but was still driven a short distance every day over the summer.
    I bought a kill switch to cut the batteries off when there not in use.

    I'm wondering how can i wire it up to kill the two batteries with the one switch, don't have much experience with this kind of thing so any other tips and a bit of detail would be appreciated.


    Thanks

    Easiest and safest way to do it IMO would be to run the earth from one battery over to beside the other one and break that circuit.

    BTW have you checked the alternator? Sometimes the diode packs can cause a drain when they start to fail

    Cheers.

    Yea got the alternator checked and was told it was fine, hopefully killing the battery will do the job.

    Any other tips for me, sounds easy to do but not sure, thanks

    It might be easier to fit the kill switch to the earth lead from the engine or gearbox to the body, depending on the type of kill switch. Do you have any picture of it?

    Slightly OT:
    What we're describing here is technically an 'Isolator Switch'.
    It 'isolates' the battery from the rest of the wiring system.

    A 'Kill Switch' has some extra gubbins (a diode, if I recollect correctly) that stops the engine from running on under the power supplied by the alternator when the switch is turned off when the engine is running. It 'kills' the engine.

    If you 'intercept' the feed from the ignition to the engine and install the isolator there, then you will have what you want. It will either kill the engine, or prevent it from starting.

    I didn't want to be pedantic with the OP, so I accepted that what he meant was an isolator switch and made my suggestion about the earth lead on that assumption.
