Electrical problem
2002 Toyota Camry 4 cyl Front Wheel Drive Automatic 100K miles

Mine is a 2002 Camry conquest, done 100000kms. Regularly serviced and in very good condition. Recently noticed that the battery light slowly comes on sometimes while driving and then after a while goes off by itself. THis is not consistent with anything like switching on head lights, A/c etc. Battery is showing as "charged", fuses etc are alright when checked. Could this be because of some battery charging electronics malfunctioning?

Get the battery and alternator load tested, this will tell you if there's a problem with the alternator and battery. Also could be a loose or dirty contact connections
