No, because you need a battery to run your car. Doing so can ruin the alternator.

What causes the battery light to come on 2000 cavalier?

The Battery? No, not typically the battery. That means that the alternator is not charging the battery and IF the engine is running, it's getting all of it's electrical energy from the battery. It means that once the battery charge is depleted, the engine won't run again until you recharge the battery.


Why would a 1999 Chevrolet S10 Blazer dash gauges and dash lights go nuts and engine run badly?

Had the same problem on two occasions with my 99 Blazer...sounds as though your alternator is going bad. The car will run good while the battery is charged up, but as the battery wears down, the engine will run poorly and the gauges will operate erratically. Eventually, the battery will not have enough energy to allow the engine to run, and it will stall.


If your battery is completely dead can your car cut off while driving?

Engine Failure to Run if Battery is "Dead"Yes, a dead battery can not provide adequate electrical power to the ignition system and thus the engine cannot continue to run. Depending on the vehicle and electrical system, this can happen, even if the battery is not dead, but only to "low."


Why will the battery not run out if the head lights are on when the car is on a long journey at night?

Because even though the electronics in the car run off the battery the alternator is constantly putting a charge back in the battery as long as the engine is running.


Could a bad coil keep the alternator from charging the battery?

Yes, because a bad coil will not allow the engine to run. But if the engine is running then the coil has nothing to do with the alternator charging the battery.
