Problem with the charging system.
usually shows low battery....
Like, maybe, the battery's getting low?
A flashing (blinking on and off) orange light indicates that the battery charge is low.
An orange blinking light on a Nintendo DS typically indicates that the system is in sleep mode or that the battery is low. If the light is blinking while the device is on, it may suggest that the battery needs to be charged soon. To resolve this, connect the DS to its power adapter to recharge the battery. If the issue persists, it may require further troubleshooting.

The light on your device may be blinking to indicate that it is receiving or transmitting data, or to alert you to a notification or a low battery.

Possible slipping drive belt or more likely the alternator is on the way out
A blinking red light is the adapter's way of informing you of a low battery.
It means the device is on. I know the device is on and fully charged but the power light should be blinking green not red. Why is the power light blinking red when it should be blinking green??
It could mean anything from "your battery is charged" to "the regulator circuit has failed." Unplug the charger and consult the manual, or check the manufacturer's website.
