Can a bad alternator cause a car to not turn over?
If the car struggles to turn over then that indicates a weak battery or a bad alternator. You can still drive around for a short while with a bad alternator if the battery is strong. Check the battery gauge on your dashboard if you have one.
Why does the battery light come on after the alternator is replaced?
This would make the Battery Light come on. It is also possible that there is a problem with the fusible link or the alternator fuse for the charging system.
Which is easier to replace battery or alternator?
It is much easier to replace the battery than the alternator. Having an expert test the alternator and battery together is the only way to know for sure if either or both parts need to be replaced. Mister Fixit: Alternators- What are they, How do they Work, and What Beaks?
How often does a car alternator need to be charged?
Alternators and batteries do not last forever, and each have their own lifespans. A car battery will last from 2 to 5 years, depending on how often you drive and the climate where you live. Batteries generally last longer in colder environments and shorter in hotter environments. Alternators will last about 7 years or every 80,000 miles.
Why does my car not start with a new battery and alternator?
With a new starter, battery, and alternator (assuming you have not drained the battery attempting to start it), the starter should attempt to crank over the engine. If the starter does not make any noise when the key it turned to crank over the engine, you have an issue with the fuses, or the circuit.
What did I do when my alternator died?
I was driving on the freeway and my car started to make a weird noise. Pulled over to the next lane for the next exit. It automatically died and locked up. I kicked it in neutral and forced it onto the shoulder. Roughly a week or two before that I replaced the alternator and it was running great.
What should I do if my alternator starts smoking?
If it starts smoking once the battery is hooked up to it, I think its safe to say you need a new one. When you jumpstart a vehicle, you are only supposed to turn on said car. Not run the car with the cables connected. You said you did it to “charge” the battery, but that is the Alternators job in the first place.
What causes an alternator to go over base voltage?
If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
