This can be a sign that the voltage regulator is not working properly. First what is high. A normal battery is between 11 volts and 13.8 volts. When the system is charging a reading of 14 to 14.5 volts is not uncommon. With the vehicle off and the switch turned to on you should see the normal battery voltage. Vehicle gauges have been know to be off due to many different things. Over charging a battery can cause it to explode. I would look over the above information and if it is showing that it might be over charging (above 14.5 volts) get it checked and fixed really soon.

If the gas gauge is stuck in one spot on a 1997 Ford Escort how do you access it to try and fix it?

check the fuse, it should be linked to other devices in the vehicle if you've noticed other components (radio, interior lights, etc.) not working. if the gauge is pegged in the super high or low position and the fuse is good, pull apart dash and check voltage reading at gauge wiring (you need voltage values from ford to determine if the gauge is out or if it is indeed telling you the right reading). If the gauge wiring checks out, the sender unit on your fuel pump went out and it is integral with the fuel pump itself. Ala, time to replace the fuel pump. Good luck.
