Would a bad alternator cause the truck to stop running?
Yes, the alternator provides electrical energy to keep the battery charged. If the alternator isn't functioning, the battery will discharge and there will be insufficient electrical energy to operate the ignition and other electrical components. Understand that a battery is only an electrical STORAGE device. Electrical energy is produced by the alternator. The function of the battery is to provide electrical energy for NEXT time you want to start the engine. Once the engine is started, the alternator must take care of all electrical requirements of the vehicle as well as for providing enough additional electrical energy to replace electrical energy to the battery that was last used when the engine was started.
How do you get the alternator to turn over?
The alternator is run by a belt connected to the engine. When the engine is running the alternator is turning. The alternator is what produces the electrical current that charges the battery & powers everything electrical while the engine is running. the battery is mainly to start the engine.
What causes a 2003 Sunfire engine to keep dying when the battery is not dead?
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
What causes battery drain in Honda rancher?
The main cause of battery drains is a bad electrical system. The electrical system is normally powered by the alternator and once the alternator goes bad the battery has a hard time holding a charge,
How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
Why after on 2-3 days of installing a new battery the car lights will dim and wont start?
A battery is only an electrical STORAGE device; when functioning properly it stores electrical energy.On the other hand, the ALTERNATOR produces the electrical energy to operate all of the electric components in the vehicle AND sends additional electrical energy to the battery for storage so that the starter can function NEXT time you want to start the engine.If the alternator is not functioning properly the battery will eventually discharge. That doesn't mean anything is wrong with the battery, it just hasn't been given anything to store. Have a reputable auto parts retailer test your charging system for you.At this point you should be suspicious of the alternator.
The alternator is considered to be what part of your cars system?
The alternator is part of the electrical system. It is what charges the battery and keeps it charged.
What does it mean when the battery light comes on a 1997 dodge avenger?
have an alternator, battery, and electrical check to find out what the problem is. battery may not be taking a charge, or the alternator is not putting out enough voltage.
Why alternator will not charge battery on 2005 ford focus... New alternator new battery replaced already?
Voltage regulator or loose wire.
What is the battery power in a car used to activate?
Pretty much everything. It provides the spark for the spark plugs, the power for all electrical and electronic components, etc. The alternator doesn't take over for the battery once the car is started - it simply keeps the battery charged.
How do know if the starter is bad versus the alternator?
First, I'm not a mechanic, my information is accurate so far as I know but I could be wrong. I will assume you realize that these two devices (alternator & starter) are not dependent on each other. I do not think the alternator needs to be good for the starter to work. If your battery has sufficient charge, then a starter motor in working order will function even with a bad alternator. To see if the starter is working, I believe, at least on older cars, you can hard wire the battery directly to the starter motor to see if it will crank over the engine (make sure the car is not already running). To see if the alternator is working, with the car running, check the voltage. Then run the car for a while with electrical components on (Lights, Radio, Fan, etc.) Then turn the electrical components off and check the battery voltage again. If the voltage has not gone down, your alternator should be working well enough to keep your battery charged. If the voltage has gone down, it should start going up as the alternator charges the battery up to it's designated voltage. (usually about 12v for most cars).
What can be the reason for a car to loose electrical power?
The alternator might not be charging the battery
