Why is the battery light on but charger is off?
The battery light is on but the voltmeter says 13.5 to 14.5 volts depending on the engine revs. When engine is off the volts drop to about 12. My mechanic says that the alternator must be charging – but why is the light on? Assuming that the voltmeter is correct and reads 13.5v to 14.5v, what could be the problem?
Why does my battery light keep flickering on and off?
If the battery cables are not connected tightly, arcing occurs between the battery cable and the battery terminal, and corrosion can set in. Eventually the connection starts to break down and voltage drops off. The effect is similar to a low battery.
