Why does the alternator Battery Light stay on?
The “battery light” indicates that the alternator delivers enough energy to recharge the battery.

The same is valid for the oil pressure warning light.

If the battery warning light stays on with or without the engine running is an indication of an alternator/ generator or voltage regulator problem. If left in that condition will eventually discharge and kill the battery.. In old cars, the warning lamp was connected to the excitation (field) coil of the alternator.
