The D indicates the discharge side of the guage, and when the indicator needle is located anywhere in this area indicates that the alternator is not creating enough current to charge the battery, and therefore, the battery is being discharged. The C indicates the charge side of the guage, and when the needle is in this area, it means the alternator is putting out enough current to charge the battery. A needle right in the center indicates that the current going into the battery equals the amount of current being taken from the battery by your vehicle's electrical devices. The closer to the center, the lower the amount of current is flowing, and conversly, the farther to the edge [closer to the D or C] the greater the amount of current flowing, whether it's a charging flow, or a discharging flow. Therefore, when the battery is being charged, the needle should be somewhere between the center [no flow] and the C.The closer to the C, the greater the rate of charge to the battery.

What could be causing the the battery light to stay on after replaceing the battery in a 2003 Ford Expedition?
The battery light comes on when the alternator is not charging. Changing the battery did nothing. Either put a gauge on the battery to see if it is charging, or while running, disconnet the positive cable from the battery. If the car dies that means the alternator is not charging. Most parts stores will check it for free. Oriely's , Autozone, etc.

Why is the in dash volt meter in my 1991 Chevy S10 only reading about 10 volts with a new battery?
The voltage gauge on the dash refers to the charging system voltage. What this most likely means to you is that your alternator is not charging properly. If the battery is new and all battery and alternator connections are good and corrosion free you can be relatively sure the alternator has failed.

Weak battery, or weak alternator.
Why does the battery show over chargeing when the engine is turn on?
Two possibilities: 1. the gauge is poorly calibrated. Check the actual charging rate using something a little more accurate. 2. If the alternator is actually over-charging, it's a regulator problem. The regulator is INSIDE the alternator and controls the rate of charge.
