    So went out to change the bedding today
    As I opened the door I noticed a very low humming noise.

    Soon realised that SOMEONE* had left the hab electric on and the water power on.

    Night before last we had a snap frost, so the auto water dump valve had opened

    Of course that meant the bloody water pump fired up and dumped about 20 gallons of water out through the valve.. No real problem but of course, once all the water was gone the pump still kept running :Doh:

    Fortunately, and much to my surprise, a quick refill and the pump was still working fine even though it had been running free for at least 36 hours

    In turn of course, it had almost flattened the hab batteries .. a pair of 130aH jobbies

    Fortunately ( again fortunately ) they had not gone below critical.. went down to 12.2 v so not THAT bad

    Plugged in the EHU and thought that was that.. About an hour goes by and I decide just to check all is ok.
    Checked the battery voltage and it was STILL at 12.2v :Blush:

    A further check and I found that the actual charger was not doing anything !!

    Sooo
    Strip the drivers side seat out, pull out the charger ( not easy !! ) and started checking wires.

    Nothing obvious but then........... then...................... The :Doh: moment

    When I fitted the pair of 130aH batteries I had had to modify where they sat as they were so much bigger than the pair off 110's they replaced

    I had, during the process, hit the small on off switch on the end of the darned charger !!

    Basically I have been running everything ever since Lincoln on battery and solar panels..

    I did wonder why, after a four days away two weeks ago, the batteries were not full when we got home ( site was only 14 miles away ), even though we had been on hook up for the 4 days.

    An interesting morning, all brought about by my own cock ups !

    It must be reassuring that the system stood the onslaught and came through it unscathed.:thumb:

    Welllllllllllllllllllllllllllllllllllllll.............

    I would point the finger, especially as she was the last person in the van, but I gotta be honest and say it is somewhat unlikely to have been her rather than me :Doh:

    If I could have thought of ANY reason she might have turned on the water then 100% would have been womans fault.. but as I canna................. :Blush:

    Mind you, at least the tank has had its yearly drain and flush now.. Will save me doing it in December :thumb:

    I'm sure a man of your immense talent could rig up something to stop the pump before it starts pumping air. No idea how it works gravity or pump dump but why is the pump not stopped when the dump valve opens. Could be a fire hazard.:thumb: Or am I talking balls.:Smile:

    The dump valve is a simple mechanical thing.. There is a bi-metal strip inside the valve that clicks over when a certain temp is reached..

    Yes, it would be handy if the pump cut off if it was free running but to my knowledge there is not one made like that.. And the chances of someone who is as big a plonker as me doing the same thing is pretty remote.. No more risk of fire hazard than leaving a light on ( in fact less as the free running pump generates no heat and draws very very little current :thumb:

    All seems fine now.. While I was at the van just now checking the batteries are coming back up, I double checked everything was turned off, the dump valve I opened manually and also opened the taps ( something I do every year anyway ) ..

    Our pump will not run if the tank is showing empty, must be the ECU that controls that. I thought the pump was buggered when it happened to me once before.

    It cannot be rocket science can it , to set something up like that?

    A simple float switch, as boats often have in their bilges would do that job, if it's floating then you have power if it ain't you don't...........that'd work.......... :Doh:
