How far can I drive my car without alternator?
How far can I drive my car without alternator?
If the alternator output was weak for a long time before it failed, the car may not go very far. If you have a fully charged high capacity battery, you could drive a hundred miles at least in the day-time, on the battery alone.
Will my car drive with a bad alternator?
The short answer is yes a car can be driven short distances with a faulty alternator. If an alternator is giving a low charge it will but a load on the engine trying to ineffectually charge a battery and the battery will slowly die as the alternator gets weaker and weaker and cannot sufficiently recharge the batter.
How long does it take for an alternator to charge the car battery?
When your car engine runs, your car alternator may take more or less half-hour to recharge the battery fully. Again on a messy road, it takes relatively one hour.
What happens when you start a car without an alternator?
Models with computer-controlled automatic transmissions will also consume battery more and let you drive fewer miles without an alternator. Start Car Engine: When you have to start your car without an alternator, a significant amount of battery energy is drained.
Can a car alternator charge the battery at idle?
A car alternator can recharge your car battery even when your car engine is in the idle stage. The car used in the 60’s century was featuring a too weak DC Generator, which could not successfully recharge the battery when the engine is at an idle stage. However, today’s car engines are powerful enough to recharge the battery even in an idle stage.
How often does an alternator need to be replaced?
How long does the alternator last? On average, an alternator fails after 100,000-150,000 miles. In cars that are driven daily, an alternator tends to last longer.

What should my alternator voltage be at rest?
To use a multimeter for testing, set the knob to a number greater than 15 on the DCV (DC volts) section. A fully charged battery at rest should measure between 12.6 and 13.2 volts. With the engine running, the alternator must exceed that voltage at the battery.
What should I do if my alternator won’t start?
In general they don’t remove and install starters and alternators, but rely on the car owner or general mechanic to do that. You might call or visit an auto electric shop and explain your problem. I agree with Triedaq and suggest you find a better mechanic.
