When a battery goes bad does it ruin the alternator?
Not likely but as alterantor keeps trying to charge a weak battery it may wear out, however as you are not likely to keep a bad battery in the car for so long there should be no damage to alternator if battery is replaced.
Do alternator your make the car start?
No, your battery supplies power to the starter. However if your alternator is defective then it will not supply power to the battery and the battery will soon be depleted.
Can an alternator charge a car battery?
That is the purpose of an alternator. The keep the battery charged and to run all the electrics on the vehicle. However it is never a good idea to allow the alternator to charge a dead battery. This will put a strain on the alternator and may damage it.
Will a car start if the alternator is going out?
It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
1993 Astra alternator light and brake fluid level warning lights both on with engine running. Battery not charging will replacing alternator cure both fluid level is ok?
Several potential reasons that your battery is not charging. It could be that your battery is too old and must be replaced. Alternatively, the electrolyte in your battery is low and that you have damaged your plates by not replacing the lost fluid with distilled water. Thus, you may have to replace your battery. Or, as you suggest, it could be a defective alternator (actually voltage regulator in the alternator). However, first you should check the belt your alternator runs off. If may be loose, causing the alternator not to charge the battery. Old belts develop multiple microcracks that will loosen the belt tension. Have you replaced your alternator belt since you purchased the vehicle (about every 50,000 miles)? If your belt is tight, it could be that your alternator is bad. Brake light could be related to alternator issue, or you have a separate problem with the brake fluid sensor. Remember to check your brake fluid at least monthly. Hope this helps.
Anyone could help you hat why your car dash box shown that the battery icon and parking icon are on and cannot turn off after ignition However sometime it was ok Someone told you it was the alternator?
Sounds like voltage regulator (located in alternator) is defective. It's the alternator. The same alerts occurred in my 2006 Sonata.
What does it mean when the odometer flickers as high as 5 mph when the car is in park and idling replaced battery due to old and wouldn't always start however will not hold charge.?
Have it tested and also have your alternator tested.
Should 2001 Toyota sienna XLE dead battery be replaced or recharged - the manual only gives directions to recharge battery - will there be side effects if replaced instead of recharge?
A battery is only an electrical storage device. If the battery is faulty it will not be able to store electrical energy. On the other hand, if the battery is ok, it could be discharged because the alternator cannot create sufficient energy to keep the battery charged. If you are able to charge the battery the problem is in the alternator or an electrical connection. If you can't charge the battery, go ahead and change it. However, replacing a good battery will only make the vehicle run briefly. If the charging system isn't working a new battery won't solve the problem.
Can a car be driving without a battery?
if you have a good alternator a vehicle will run without a battery, however I wouldn't recommend doing it. On most vehicles the alternator will charge at too high a rate with out a battery installed. This can and will damage any electronics.
No power 2000 Mercedes S500. Disconnected battery replaced starter and relay attached battery and wont start. No power in control unit?
More than likely you have a bad ignition switch however your anti-theft system could still enabled.
Can you start and move a car without battery?
The battery is used when the car is running to stabilize the voltage and store energy from the alternator. It is not recommended to run the car with no battery, as this can damage the alternator and the car's electrical system.A dead battery (if you have one) can usually suffice to run the car for a short time, however it may also damage the alternator.
What is wrong with a 1995 Ford Explorer 4wd if the battery light went on when the battery is still new?
Reasonable assumption the alternater is bad, but no gaurentee. Hi. The common misconception is that the battery is primary power source of the vehicle and it is in many ways. However, it's main function is for cranking power to the starter. All batteries have a life span from charged to dead (like any battery). The charge in the battery has to be replenished, and that's where the alternator comes in. I suspect the diode in the alternator is bad and the alternator will have to be replaced. A word of caution: if you drive the vehicle for an extended period of time without the battery being charged, a 12-volt battery will be reduced to 9-volts, and at that point systems in the vehicle will shut down. If the battery light is on, the charging system has to be checked to be sure that it is functioning. There are other possibilities that would cause the battery light to come on, however in this case I strongly suspect the alternator. your fan belt could be slipping
