Dunmowin Posted August 11, 2011 Report Share Posted August 11, 2011 We have a 21ft ATV, which we normally run off 12v, however, when we do run on power (240v)we notice at night that the power supply(which is directly under the head of our bed) hums whenever the vitro fridge starts up which is regularly throughout the night.WE have temporarily solved this by switching over to 12v at night, does anyone have any other suggestions?regards"Dummowin"currently in Barcaldine Quote Link to comment Share on other sites More sharing options...
TonyH Posted August 11, 2011 Report Share Posted August 11, 2011 I always leave mine on 12v regardless.... if I'm on 240v or not... a certain person at the factory told me to do this Quote Link to comment Share on other sites More sharing options...
joyngeoff Posted August 12, 2011 Report Share Posted August 12, 2011 Hi DommowinWe always leave ours on 12v even though we have our bed east west at the rear and get no noise from transformer or inverter in the boot.We sometimes hear a slight hum in the kitchen area from the transformer if we switch to 240 to give the batteries a bigger boost whilst on power.

Danny and Sue Posted August 12, 2011 Report Share Posted August 12, 2011 Probably the battery charger.ours makes a fair noise when the fridge cuts in.I have bought a plug in timer & have set it to turn off at 9pm & back on at 9am.Lot better.

Steve and Kez Posted August 13, 2011 Report Share Posted August 13, 2011 Danny & Sue,Fantastic idea ....... It will solve our issue as well, as we have the same noise. We knew that it was the batt charger but never came up with a solution except turn it off manually.Thank you Quote Link to comment Share on other sites More sharing options...
