wingsaircharter Posted August 28, 2007 Share Posted August 28, 2007 My 99 RX300 is draining the battery when it sits overnight. It will last a day or two after a fresh charge of the origional battery. I checked and there is about a .5 amp drain on the battery when everything is off. Does anyone have any ideas or know what the drain should be if everything is functioning correctly? It shows about 12.2 volts when off and 14.2 when running both with the lighs on or off so it seems as though the alternator is working.
