I just had to replace my alternator and the battery light was coming on when I had slow engine speed (under 1000RPM)...It gave me little warning and completely failed after 20 miles, then the battery went dead and , of course, the engine stopped...
Replace the Alternator before you get stranded as what happened to myself...
check the connectors and wires first. make sure their clean and tight. if beltis tight it should be ok. have alternator tested.
It could be a loose serpentine belt. Or if the alternator is going out either way its most likely a charging problem.
Auto Zone will check your charging system for FREE. Go to any Auto Zone and have them check your Alternator / and charging system.
Remove the serpentine belt and check the belt and pulleys for damage. While the belt is off, turn the alternator by hand listening for the noise.
Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.
The battery light coming on in your Town and Country minivan means that the alternator needs to be replaced. The alternator charges the battery and if it goes bad it will not charge the battery.
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
yes i think cause the battrie runs of the alternator
Battery and brake light coming on means the Alternator is not charging the battery . It could either mean a bad circuit connection or the alternator is just shot. Have the Alternator checked.
Battery is not charging due to defective alternator or the battery itself needs to be replace.
Loose alternator drive belt or loose or corroded battery cables. The battery itself may also be bad.
Check the fusible link coming off of the battery.
It could be your alternator is going bad
I would suspect one of two things. Either the replacement belt is not the correct size or the belt tensioner is bad. The squealing sounds like a loose belt which would also account for the battery light. possible bad battery causing the alternator to work too hard
needs new alternator
There isn't a fuse for the alternator. The alternator is belt driven, and there'll be two lines coming from the alternator - one goes from the alternator positive to battery positive, and the other goes to ground.
My lights were coming on when my alternator was going out. Test your alternator and charging system and replace accordingly.
Your battery has low voltage and needs recharged, check for loose battery cables, if the light stays on have your alternator checked.
My AstroVan wont start & the neg blk wire on battery is coming up POS
IT COULD BE THAT YOUR BATTERY IS LOW OR YOU MAY NEED A NEW ALTERNATOR
A few causes that will make the Battery Light come on are: 1. Faulty Battery 2. Loose Battery Connection 3. Battery is not Charging, ie. Faulty Alternator
Check for poor ground connection either at the alternator or follow the negative cable coming from the battery.
If your battery is always going dead a day or two after a boost, then it most likely the alternator. Two surefire ways to see if the alternator is bad is to take the positive (red) battery cable off after starting the car. If the car still runs, alternator is good. If the car stops running, then it is likely the alternator. The battery is just to turn the car on and then the alternator regulates the initial charge coming from the battery and that powers the car. Another thing you can do is to run a voltage check at either the battery or on the alternator with a Volt Ohm Meter (VOM). If the voltage comes back as 13.5V or better, than the alternator is good. Less than 13.5V, and it is likely the alternator. Be advised, though that what could look like an alternator problem could also be your ignition switch or starter.
No, the battery light is coming on because there is a problem with the charging system. Most likely the alternator is failing. Most auto parts stores will check your system for free.
i have a 97 mirage 1.5 that did the same, have your alternator and battery checked.
Alternator, silenoid, battery cables. After you have checked those 3, try a new battery if its more than 3 years old.
