    Hi.
    So Kombi has been parked up after going to Old Bar over long weekend.
    I have the ctek 5 amp on start battery. A 2 amp charger on the house battery.
    Walked outside this evening and could hear the electric fuel pump whirling.
    Investigated and found ignition lights on but key in off position.
    Removed the leads from both batteries . its too late to be outside with torches and freaking neighbours out.
    So.. Ignition switch Kaput and allowing the lights to illuminate?
    Or do i have battery issues?
    Your advice greatly appreciated.
    Many thanks.
    Pete

    Ignition switch is my first guess.......they do fail with monotonous regularity.

    Most likely ignition switch or a short circuit in your fuse box

    Kombi cranks over but wont start.
    Ran 12 volts to coil in case ignition switch was kaput. No joy.
    Ordered new ignition switch last night.
    Fuse connected to coil was found blown.
    So replaced the fuse 8 amp.
    Thinking electronic ignition could also be fried....
    Will go and order a replacement now.
    Leaning to a Petronix 2 module.
    Once i have these i will replace both for further piece of mind.
    Continueing the search with fuel shut off relay.
    Also checking electric fuel pump and corredponding relay.

    Try a different coil, it's possible it burnt out if it was powered up for some time...

    Fuse connected to coil.....is it the one on left in engine bay that runs to gearbox and reversing light switch?

    I agree that dodgy switch first call.

    Excludes efi double relay as a suspect ;)

    So. Turned ignition on and metered across the ignition coil poles. 9.8 volts shown.
    Yes fuse on the left side of coil.

    So ignition switch on the way. Also order new 12 volt coil and spark plug leads. Might not need. Good to have spare set.

    Fuse on the left side of coil in engine bay is for the reverse lights

    Great to know. Reverse lights are working now with new fuse installed
    I probably blew the fuse several weeks ago installing external oil cooler frame work with remote oil filter in front of the gearbox.

    Put the old coil into the 69 beetle and it didnt start.
    Gazman was on the money..
    So all is well.

    Used to see this on older cars that had no 'ACC' position on ign switch - owners leave the ign on to listen to the radio, an hour later they've burnt the coil out and it wont start ;)
