    My motorhome's charger /12volt power supply has started to murmer with a 50htz humm. Does this mean it's on it's way out or will It just annoy me enough to change it anyway?

    Personally I would just put up with it until it either gives up or you get used to it :winky:

    Mine used to do it and it was the laminations on the transofrmer working loose. Luckily I could tighten them as they were assembled using bolts,just tightend up and added a touch of Loctite.

    You can at least disconnect and stop the humming. I have it continuously without trying:ROFLMAO: I think they call it tinnitus.
