AnswersDriveIf jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can't hold a charge when the alternator is shuts off.

Can jumping a car damage alternator?
Any battery or alternator issues that affect power quality will be transmitted to your car. The good news is that large 12v batteries make excellent buffers against power issues that might otherwise cause damage. However, it is still possible to suffer damage to your car from jumping someone elses.

Can you bump start a car with a bad starter?
If by jump start you mean connecting the non start car via cables to another car's battery then it will not help as it is still the bad starter that must turn the engine and and extra battery is not going to help. No, if the starter is bad that's it. If it's a manual transmission you may be able to push start it.

How long does it take to recharge a car battery?
A car battery usually holds 48 amps so if you take that it charges at approximately 1 amp per hour you can work out how long it will take to charge your battery with various amperage chargers. Charging your battery with a four amp charger will take about 12 hours to get a full charge out of this low amperage.

How long should you jump a car?
If your car does start, let it run for a few minutes to help charge the battery further. Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.

Why is my car not starting?
The starter won't crank. If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a dead battery; here is How to check the battery. The starter solenoid control wire could have a bad connection.

How do you clean car battery terminals?
Here, you will mix two tablespoons of baking soda with an equal amount of water in a clean container. Stir the solution to form a paste, then use a toothbrush to apply the paste to each terminal. The solution will begin to sizzle as it interacts with the corrosion. Use a wire brush to remove the remaining residue.
9
How much voltage should an alternator put out?
A car alternator needs to be putting out at least 13-14 volts (ideally between 13.8 and 14.2 volts) to effectively charge a 12 volt car battery. If the alternator is putting out too much voltage (15+ volts), it is likely your battery acid will boil over out of the battery.

How can you start a car with a bad alternator?
Use another car with a good battery to jump-start your car. Make sure that the car is turned off. Connect the positive (red) cable to the positive terminal on the car with the bad alternator. Connect the red cable on the opposite end of the jumper cables to the positive terminal on the car with the good battery.

What drains a car battery while it is off?
Defective alternator diode. A car alternator recharges the battery and powers certain electrical systems. If your alternator has a bad diode, your battery can drain. The bad diode can cause the circuit to charge even when the engine is shut off, and you end up in the morning with a car that won't start.

Can you check an alternator by disconnecting the battery?
If you're tempted to test an alternator by disconnecting the negative battery cable, don't do it. A good alternator may indeed keep the engine running, but it was never a good test. In the pre-computer days, you could pull it off without damaging anything. Today, you risk frying every electrical device in your vehicle.

How does an alternator in a car work?
As the rotor revolves it generates a higher current in the stator windings. A car uses quite a lot of electricity to work the ignition and other electrical equipment. The alternator consists of a stator - a stationary set of wire coil windings, inside which a rotor revolves.
