    Just recently, when we turn on a tap & the water pump runs, it causes the TV to turn off, due I guess to a sudden power drain? it also dims the lights for a millisecond. Can't remember it ever happening before, suggestions please? Thanks o_O

    What you describe is caused by the battery voltage not holding up. This will happen if your battery is close to being discharged or (for example) a poor connection at either battery terminal. Does it still happen when on EHU?

    I've just had the same problem with exactly the same symptoms. On closer inspection a white plastic multi- connector close to one of the hab batteries was getting hot when any substantial load was applied. (The Eberspacher on start-up, requires quite a few amps.) I suspect the connector had become loose over time. Fortunately I had a similar spare connector in the garage. Replaced and now it appears fine.

    Best thing to do is put a voltage test on battery and as stated check all connections. Bad connections cause heat in the wiring and heat in the wrong place in the van can be a bad bad thing. A charged battery should be about 12.7 to 13.5 after charging and letting it settle for a couple of hours. Battery flat at 12.0>1 volts.

    It could also be the water pump motor being on the way out drawing a lot of power. Mind you poor connections is probably the most likely although one weird one I have had was a partly blown fuse which could not carry the big current.
