2005 Ford Explorer Question: Battery Sensor Red Light On Sensor stating check Charging System 2 year old bat
Answer #1bennettr8 August 19, 2014, 08:42Rookie
Could be the charging system sensor (i.e. the sensor that tells the light to go on) and no big deal or it could be the alternator. Mine just did this last week. The light and beep happened randomly for about two days. Then the entire electrical system went dead. Replaced alternator in hotel parking lot (three 14mm bolts, one 10mm nut, and serpentine belt removal tool) and all good now.
