Check the charge on your alternater.

If my altanator goes out what will a car do?
If your alternator stops working you are powering the vehicle on your battery and your battery is not being charged by your faulty alternator so eventually as the battery drains down the car will stop running. Avoid using any electrical power...ie...lights, power windows ect and get your alternator repaired immediatley.
How do you know your alternator is going bad in Lexus gs400?
Hello, There are many symptoms of a bad alternator that you should pay attention to: If your alternator is not working properly it might affect how the alternator belt is turning. An alternator that is not working properly will make an audible sound. Removing the alternator belt can confirm if noise is coming from the alternator. Another symptom is if anything electrical slows (windows, seats, etc) or the lights dim while you are driving. Yet another symptom is experiencing difficulties starting your car. This could be an issue with the battery, so make sure that you check the terminals and note the age of the battery. If your battery frequently discharges then this is another sign of a bad alternator. Hope this helps!
What is wrong with your 2000 Toyota Sienna minivan when the battery light is on the radio cuts on and off off and the power windows are operating slowly?
Sounds like a bad alternator. Slow windows indicate low voltage (same for radio cutting in and out), the alternator light indicates battery voltage is higher than alternator voltage (most likely meaning alternator isn't putting out anything).
Opel corsa battery problems?
Check that alternator is charging battery properly and change battery to see if you still getting same issues. It can also be a leak in your car radio, burnt alternator diode, or a shorted coil in the central locking system or windows.
1998 Ford F150 won't start after it gets to running temperature. The battery and starter solenoid have been replaced. Truck has electrical power to lights windows etc?
check the ECT sensor with a scan tool
If the AC stop working while you driving and the windows stop working too its possible that the alternator is bad?
Electrical Failures But Engine Continues to OperateAlthough it is possible, it is not very likely because with an alternator failure, the battery will become discharged, and eventually will "kill" the ignition and thus the engine.This sounds more like a fuse or relay failure.
Why did your 1994 Astro Van quit when you turned on the headlights Now it won't start and the lights horn power windows dome light and radioclock memory don't work you don't hear the fuel pump running?
Check your battery, it can be weak or dead. If the battery seems fine, your alternator may be weak or needs replaced.
Why does your battery light come on in a 2005 Dodge Stratus?
Insufficient voltage from the alternator would be typical. If you have a DMM or voltage meter, test the alternator. You should be looking at between 13.6 - 14.6 volts from the alternator... if you're getting less than that, your alternator's on its way out, and needs to be rebuilt or replaced. In a nutshell, your alternator isn't sufficiently recharging your battery, and running your car is draining the battery. It'll continue to run until the battery goes dead. In a newer car, you'll notice nonessential systems start to shut off (e.g., radio, power windows and seats, etc.) as the LVD (low voltage disconnect) kicks in for the sake of maximizing battery life to run essential systems. This is something you really don't want to wait on. If you don't have the aforementioned tools, any auto parts store (NAPA, Advanced, O'Reilly, Auto Zone, et. al) will have the equipment to test your alternator, and can also help you with removal and installation.
Will the alternator affect the performance?
While a vehicle engine is running the alternator generates electricity to run the car and operate things like the radio, power windows,seats,doors,wipers, and the spark plugs to ignite the fuel making the car go. The excess electricity recharges the battery which is primarily used to start the car in the first place. Without the alternator your car will only run off the battery which will eventually run down and wear out much quicker and need to be replaced. As the battery is dieing its efficiency degrades affecting your performance until it fully dies then your car will not go.
How do you know of your car battery is dead?
Your car won't start. No electrical items will work (radio, lights, power windows/locks...)
How many amps is a car alternator?
The amperage of an alternator depends on the size of the car that's on and what all it has to power. A large SUV that is fully loaded (power doors, power locks, power windows, etc) will need a higher amp alternator than a small car without any added electrical options.
How can you tell if it's your battery or alternator that's bad?
Battery or AlternatorThe battery provides the juice needed to operate the starter motor. It also provides power to the electrical and electronic devices in your car when the engine isn't running. Every time you start your car or play the radio or operate the power seats or windows while the engine is off, you drain the battery a bit. The alternator -- which is really a generator -- replenishes the battery when the engine is running and provides power to your car's electrical systems when the engine is running. If your battery is totally drained, the car will fail to start. You may be able to "jump-start" the car using another vehicle. But why is the battery dead? If you left the lights on, even a small dome light inside the car, that could have drained the battery. Jumping the car and then letting it idle for a while can replenish it, but if the battery is old and near the end of its service life, it may not be able to take and hold a charge any longer.Or the problem could be the alternator. Perhaps it is no longer able to recharge the battery. If that's the case, the battery -- even a brand new one -- will eventually run down, and rather quickly, because your car's electrical system will be running off battery power, instead of from power supplied the alternator. When the battery goes dead, your vehicle will stall, because there is no power to run the electrical systems.Answerwith the vehicle running(even if you have to jump start it), remove one of the clamps off of the battery. if the vehicle dies immediately, you have a bad alternator. if it runs for a little while before it dies, a bad battery. This might have worked on a car thirty or more years ago but is actually potentially very harmful for a modern car. The cars now are designed to have a battery as an integral part of the charging system and if it is disconnected can send voltage spikes through the system and burn out your computer. Also the alternator is designed to put out a certain amount of current and this test would only tell if the alternator is putting out enough current to keep the engine running, not if it puts out enough to keep the battery charged, run the lights etc. The only real way to tell if the alternator works is to put a voltmeter on the battery and see if the voltage goes up after the car is started. Then to tell how well it works, put an amp meter in line with the alternator and see how much energy it puts out when the various circuits are turned on.A bad battery can be hard to detect sometimes. It can work fine then all of a sudden fail to start. Then next time you try it works fine again. The best way to test it is with a load tester at an auto parts store or shop.
