Does tachometer has to do anything with the charging of a battery while driving a car?
The tachometer DOES NOT have anything to do with charging the battery in a car at any time. The tachometer simply reads, and relays to the driver, how fast the crankshaft in the engine is turning. This is displayed in RPMs, short for "revolutions per minute" representing one complete revolution of the crankshaft. On some newer cars, the tachometer may share a signal from the crankshaft sensor with the ECU(the car's computer) as well.
The charging of the battery is handled by the alternator or generator which is most commonly belt driven and attached to the front of the engine. It may have gauges in the dash such as a Voltage gauge, Ammeter, or just simply a "dummy light" that illuminates and warns the driver of charging problems should they arise.

What causes headlights to dim while driving?
Your battery is weak, or your your alternator is not charging battery.
Be careful when charging lithium batteries while driving?

If your battery is overheating and you can smell acid what should you do?
Stop driving until the charging system and battery have been checked for an overcharging condition.
Why did your battery light come on while you were driving?
Charging system problem. Normally this means there is a problem with the alternator.
What causes a car battery to die while driving?
It has to be a dead charging system.... usually a short internal in the alternator
How long should a fully charged car battery last driving in daylight if it isn't charging?
About 2 days
Why does the battery light come on while driving even though the alternator is charging the battery?
The alternator may not be charging it enough. With the engine running at an idle check the voltage at the battery with a DC digital voltmeter. It should read from 13.5 to 15.5 Volts. Anymore, or any less, and the alternator is suspect. You might also have a defective battery.
Why does the battery voltage fluctuate from 14.4 volts to 12.6 volts and back again while driving?
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.
Your 1997 cirrus only starts with a jump while driving battery lite stays lit?
battery light indication means a dead battery or a dead alternater/regulater or a fault in the charging/ignition system
Will a faulty tps cause the tachometer to fluctuate while driving?
no it will not!
What happens what the battery light come on while driving your car?
It usually means that your alternator (or generator) is not charging the battery. At this point you need to check system voltage with a voltmeter when the engine is running. You should see at least 13.5 to 14.5 volts. If it is less than that, it is not charging. You can also have the charging checked at a repair shop if you don't have a voltmeter.
How do you check if my TomTom is charging?
To check if your TomTom is being charged,connect the charger ,power on the unit , tap the bottom right of the Driving view to get to the route summary screen. If the battery is being charged, the word Charging is shown under the battery symbol on the right. If you don't see the word Charging, the battery is either fully charged (indicated by a completely filled battery symbol) or it isn't receiving external power.
