irokin Posted July 22, 2008 Report Share Posted July 22, 2008 Just means you're alternator isn't keeping up with the power demands of the demister so its drawing from the battery. They do drain A LOT of power. If you want to keep the charge light off just find a bigger alternator. Quote Link to comment Share on other sites More sharing options...
DouggehKE30 Posted July 23, 2008 Author Report Share Posted July 23, 2008 Thats what i thought to start with, but..... I can have everything including my amp(sucking the life out of my battery) hightbeams, windscreen wipers etc(basicly everything) on and the light doesnt even flicker. But if i turn every thing off and just only the demisters on, the light says hellow. So I didnt think that power was an issue. Or am i still wrong and need better alternator?

silverra23 Posted July 23, 2008 Report Share Posted July 23, 2008 You would be staggered how much current the demisters draw. Could well be as much as everything else put together. Still sounds like an alternator not keeping up with the power requirements. Try either a reco one or bigger amp alternator. Quote Link to comment Share on other sites More sharing options...

turbo ke20 Posted August 27, 2008 Report Share Posted August 27, 2008 put a volt meter on the battery and see what happens to it when you turn the demister on. it should not drop below the battery voltage. if it does you have a alternator or regulator problem Quote Link to comment Share on other sites More sharing options...
