I have a 2003 Hyundai sonata my starter and battery is good but car won't start. All the lights come on and it turns over with a clicking sound could it be my alternater?
The clicking sound means the battery is low not 12.6 volts have it load tested make sure the battery connections are clean and tight,along with ALL ground straps. NOW you can test or have the ALTERNATOR tested for output with the car running use a multimeter voltage at the battery terminal should be 13.2-14.8 volts OK
If it is just one loud click then it is the starter, but if it is a series of clicks, then it is low voltage, could be a battery or even bad battery cables.
