  • Appreciate without seeing / knowing further info a difficult one but just any ideas.

    Camper is hooked up to Camp site electrics — Electrics box in Camper shows power is connected and all good.

    However just come to start van — ignition on fine but just won’t start — rapid clicking noise and just won’t start.

    Never ever had this issue, just wondered if any ideas — anything obvious to check

  • Sounds a flat starter battery.

    So it would seem that your EHU conection is only connected to your leisure battery and not the starter.

  • you will need to jumpstart the van,

    or connect a battery charger to the starter battery,

    running it low/flat will damage it.

    more info below.

  • Green flag are on their way.

    Leisure Battery is fine and full.

    So presume something is draining the van battery — just doesn’t make sense what as nothing really to drain it.

    Sorry I know little help with little info. Doors are open all the time but the interior lights wouldn’t drain would they — they turn off after a few mins anyway.

  • I’ve unplugged the EHU — you can see shows leisure Battery fine, if I plug EHU you in Charger Supply light comes on so all good. Leisure Battery under drivers seat.

    Perhaps EHU is a red herring if all ok, in which case why the drain on the van Battery? But have no tools to see if drain etc

  • Thanks — as above think it’s a red herring was just my initial thinking.

    Nothing running of 12v, no radio. Assume interior lights independent of Ehu — we’re in and out of the van loads — though tend to leave doors open — lights switch off after 15 mins — would the battery drain that quick off just interior lights?

    Van will be 5 years old in Sept — but van is used pretty much every day..

    No multimeter, hopefully Green Flag here in a few mins, see if they can give any advice..

  • every time you press they or open the van door the systems power up.

    the internal lights come on,

    the door locks power open/close.

    the modules power up.

    This can flatten the starter in a day or so as all the above is powered from the starter.

    the fix is easy . . .

    just fit and additional EHU mains powered charger to the starter: ( so that whenon EHU the starter is kept at 100% )

    like this NOCO 5A version . .

    NOCO GENIUS5UK, 5-Amp Fully-Automatic Smart Charger, 6V And 12V Battery Charging Units, Battery Maintainer, Trickle Charger, And Battery Desulfator With Temperature Compensation : Amazon.co.uk: Sports & Outdoors

    if you have decent leisure setup — then you can back feed the starter battery from that . . .

  • All, sorry for the delay in updating.

    Green flag arrived — started in less than 10 seconds. Very frustratingly he didn’t hook up a multimeter to check things as supposedly already had 3 jobs waiting — wasn’t worth getting into an argument plus we were planning on going out so did that and it gave the battery a good charge.

    So none the wiser — perhaps it is all the opening of the door etc — never been an issue before but then the battery is older so possibly struggling.

    Let’s see what tomorrow morning brings.

    Thanks for the help and suggestions — looking in to those.
