A battery is used to start a car. Once it is running, the alternator then supplies electrical energy to charge the battery as well as power the electrical systems in the car. Removing the battery while the car is running will not affect the running of the car.
If your alternator is good it should stay running until your engine dies from no fuel.
it should because car is running off alternator and if you do this it will not charge battery back up
Alternator not charging battery sufficiently? Check with a voltmeter: A fully charged battery should read approx. 12.8 volts without engine running. With engine running should read approx. 13.8-14.2 volts
Check to see if the alternator is charging the battery properly. Use a voltmeter - if fully charged battery should read approx. 12.8 without engine running Should read approx. 13.8-14.2 with engine running if alternator is working properly
It could be a bad battery or regulator. To check the regulator to see if it putting out the correct voltage check the battery voltage while the bike is running. It should be around 14 volts.
Does alt. light stay on after car is shut off? If so could be voltage regulator is defective and overcharging battery when running Does light stay on after car is shut off? If so could be a bad voltage regulator--if so may be overcharging battery Check voltage readings at battery should be around 14.2 with car running -- if much higher than this voltage regulator is bad.
The computer's power, or its ability to stay powered on and running, is maintained by the charge in the battery. The battery's electricity is used by the computer to keep running. If there is no charge in the battery, or the battery is removed, the computer will shut off and will not be able to be powered up.
you can but it wont stay running if the battery is dead
Why do you want to unhook your battery??? If the alternator is good the car will continue to run, if it dies then you have a bad alternator this is why you would want to unhook the battery cable to check and see if you have a bad alternator
Because the ignition is powered directly from the battery. The Gen/Alt only feeds the battery.
That light doesn't mean that your battery needs to be replaced. It means that your battery is not being charged while the car is running. Have your alternator tested.
Sounds like a dead battery. You need the battery to start the car, but once it is running the engine runs completely off of the alternator (which also recharges the battery if the battery is still good).
