It will do no harm.
No , just when the engine is running
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 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
The alternator - it provides a charge to the battery while the engine is running.
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
Car batteries recharge themselves while your car is running. However, if your battery is dead, you must jump the battery using a battery jumper box or jumper cables attached to another vehicles's battery.
the car battery. the alternator while running
If the car won't start, jump it off. While it is running, remove the positive cable from the battery. If the car dies, then your alternator is bad. If it keeps running then you may have a bad battery.
Your alternator is probably not keeping the battery charged while the car is running. You need a new alternator!!
Probably the alternator or its drive belt has failed
means that your alternator is not working. It is either bad or your belt is not tight.
