The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.
Because the alternator keeps the battery charged when the car is running.
probably has a bad alternator. With the car running use a digital multimeter an you should have 13 + volts (as high as 14.5+) at the battery terminals if the alternator is working. If only 12 volts or so then check the alternator.
The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.
It sounds like your alternator is no longer recharging your battery. You probably need a new alternator.
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
AnswerIf the battery's dead it could be the alternator or a bad battery. If not, the starter. Try jumping it. If it starts the starter's OK. Then investigate the alternator and battery.Does it turn over but not start..?? There is a difference. Doesn't turn over would most likely be the battery, which is typically followed by a clicking noise. That would be the starter solenoid trying to engage but the battery doesn't have enough power to do so.If jumping it starts it right up, let it run for 10 or 15 minutes then (while running) check the voltage at the battery terminals. If it's above 14 volts, the alternator is doing it's job and the battery is dead. If the voltage is less than 14, then the alternator needs to be replaced.
Alternator is weak and needs replacing. Drive belt on alternator can also be slipping due to being loose. Check the alternator output at the battery with the engine running. It should read from 13.5-16 volts DC. Any less and it needs replacing.
Blown fusable link?Bad ground cable?Bad alternator - vehicle running off battery and battery drained of all power?
MAYBE IT COULD BE A BAD SENSOR. IF IT IS RUNNING GOOD I WOULD JUST IGNORE IT.
Check battery cables and alternator wiring for looseness and/or corrosion. Weak alternator--can't keep up with battery load. Check with a voltmeter A fully charged battery should read approx. 12.8 volts withou engine running With engine voltage should increase to approx. 13.8-14.2 volts. If not in this range replace
Probably need an alternator. Check your battery voltage with a multimeter, without the car running it should be around 12.5 volts with engine off. Start the car & check the battery voltage and if the alternator is charging properly it should be 13.5 or better at the battery. If not check the power terminal at the alternator itself and if only battery voltage (12 or so volts, same as battery) is there then the alternator is not charging.
Have you cheked your alternator? The battery only starts the car and runs electrical components such as your radio and A/C and lights. The alternator is the generator that keeps the engine running once it has been started. Mine was the fuel pump went out
Yes. The alternator is used to keep the battery charged, while using the headlights, radio, a/c, etc. The starter to me is misstated because it actually cranks the engine. The ignition system starts it, and keeps it running.
Ignition switch is going bad. Will have to replace it. Because eventually the truck will not restart at all.
Check the alternator output with a voltmeter Without engine running and a fully charged battery reading should be about 12.8 volts With engine running reading should be 13.8-14.2 volts May be a bad alternator
That could be the alternator or the battery. Try jump starting your car with another car's battery. If it still does not start, it is probably the alternator. If it starts, your battery is dead.
If your car doesnt start, it could be the battery. But if the car starts and you unplug the negative cable and the car turns off, its the alternator.
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
You either have corroded battery terminals (where cables hook on battery)or a bad alternator ...Autozone willtest for free
proably yes if not its probably something with your battery or alternator
Possibly a bad alternator or battery.
Sounds like the engine is using the battery as the source of power instead of using the alternator. The main job of the battery is to give power to the starter that "starts" the engine. Once the engine is started the alternator kicks in to maintain power throughout the vehicle, as well as keeping the battery strong. But if the alternator isn't working, the engine will get it's power from the battery. And without the alternator keeping the battery strong, the battery will die. Note: between the alternator and the battery, there is a voltage regulator, this make sure that the battery only gets the power it needs. Oh, one more note, here's a way to tell if the alternator is working properly. (Start the engine, while it is running remove one of the battery cable for just a few seconds.)if the engine stops, then you have an alternator problem still. Check your wires. Or replace the unit. for more answers. email email@example.com A constant 12 volt drain on the electrical system, even when the car is off
Change the alt.
It sounds like the starter is bad. The clicking you hear is the solenoid trying to kick-over the starter. If the vehicle starts but, won't stay running, it could be the alternator, or the wireing to (from) the battery or alternator (most likely the ground wire). Or it could be the dreaded MASS AIRFLOW SENSOR!!!!
