Want this question answered?
A short in the turn signal wiring can cause the voltage gauge to fluctuate. A loose ground wire can also cause the gauge to fluctuate.
12 Volt. Next time, be more detailed on your question.
voltage regulator, sometimes its in the alternators, advance auto parts doesn't replace them in remanufactored ones.
Have
Voltage may fluctuate due to improper wiring/groundings or sometimes due to sudden load changes. So as to give constant output voltage we need voltage regulation. If we let the voltage to fluctuate then it might cause damage to the equipments
As little as possible
battery produces voltage by
check your fuses if they are good the voltage regulator is in the pcm eng computer

The battery in your car does not constantly charge while driving. Electricity is needed to run the headlights, starter, radio, etc. In order to save wear on the alternator/generator, the battery is sometimes used to power these electrical devices as your car's internal sensors see fit. When the battery's charge drops below a certain voltage, the alternator kicks in again to keep the battery at its optimum level.
You need a new battery. The same exact problem just happened to me in my 2002 jeep grand cherokee. The computer in the vehicle wont let it run unless it is getting a high amount of voltage from the battery. When you replace the battery, the problem should be fixed.
I took the vehicle to the dealer service department. It turns out the vehicle battery was not providing the correct voltage. Once the battery was replaced, vehicle is running properly again. In the future I will check battery condition / voltage first.
