    Noticed today that when the power is switched off, no mains or battery there is a clicking sound coming from a relay box under the sofa. I then put the power on it stops, turn the power off it starts again a few mins later. It doesn't do it if the alarm is armed. I have only noticed today. Any ideas? It sound like a very loud clock :-(

    I bet most of us have the same but never turn everything off :D

    No idea what is causing it, but why turn everything off?

    Not sure, thought the power was turned off when not using the van. Is that not meant to happen? Does the battery not drain if left on?

    I guess all MH's will be a bit different, but my logic says if nothing is in use there will be no drain

    We are lucky though and keep ours at home on permanent hook up

    I hope I am not just adding to your confusion, do not presume all of us here know much more than your average newbie :D there are some very clever ones though, someone will help you and put me straight

    I had the same thing happen a few weeks ago with my Ducato van conversion, it turned out to be a faulty relay which I had replaced with a more heavy duty one by a local auto electrician, problem solved !!

    So i persume at the moment no damage will be done if left for a bit? I will contact our dealer and ask if i t can be looked at when we are next in the area.

    Just a thought but on my heater if the switch for the gas isn't turned off fully it keeps trying to ignite which sounds like a time bombe ticking

    Odd why it does not happen if the alarm is set

    After more investigation it does happen when the alarm is on. It turns out nothing to do with the alarm, i phoned the alarm people and their electric is no where near it. So phoned dealers and they suggested bringing it in for them to check it out. Keeping it plugged in for now as don't want it clicking all t he time just in case it causes problems.

    This reminds me of when our relay box wasn't right - odd clickings when there shouldn't have been any. We had problems with the fridge running on 12v and had to get a new relay box.

    When you say it settles down when the power's on do you mean mains power as in electric hook up, or 12v as in leisure battery power?

    Also, some gadgets may operate completely independently of the control panel but still put a drain on the battery. In our case the fan for the blown air heater could drain the leisure battery if mistakenly left on long enough, even when the 12v supply was turned off at the control panel. Have you switched everything off?

    I think your alarm is most likely to be running off your engine battery, not your leisure battery.

    Do you have a solar panel on the roof?

    My gut feeling on this is that your relay box may be trying to protect your leisure battery voltage from getting too low, but it's only a guess and I'm no auto electrician.
