Brake and battery lights turned on


I'm sorry but there isn't a line going from your alternator to your brake Master cylinder. The brake fluid is in a contained sealed loop and it is used for hydraulic pressure, it does not flow out of the master cylinder and lube the alternator bearing. Yes your brake light could be on because it's low on fluid, if your alternator is squealing, it could be because of a bad bearing but, I'd look at the serpentine belt tensioner first, it could be weak, I'd also look at the condition of the serpentine belt itself. If the belt has never been changed that means it's 12 years old and probably worn and cracked.

My 1994 Sedan Seville needs an alternator how do I change it


The alternator in your car is one of the easiest fixes you can do. First, remove the NEGATIVE (-) battery cable.
You must relieve the tension on the serpentine belt by loostening the retaining bolt, then remove the wiring harness plug from the back of the alternator, then remove the two retaining bolts from the alternator. Reverse the procedure to install the new alternator, making sure that belt tension is adequate. Replace the netgative battery cable last, and test.
If the serpentine belt is loose, replace the belt.

New battery drains.


I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

My car was sputtering withe battery light on. I checked the battery, and it was fine. The alternator was going out. I changed the alternator and put all serpentine belt on correctly. Now when I turn...


Is the alternator putting out 14+ volts when it is running? If so is it a cheap alternator? The bearings might be bad. Could be water pump or anything the belt drives such as the A/C. Have the battery tested ASAP then the alternator.

Remove and replace alternator


Hello,

Just follow these steps to remove and replace the alternator. You will need this tools, Serpentine belt tool, Battery wrench, Lug wrench, Floor jack, Jack stand, Socket set,

  1. Open the hood, locate the serpentine belt tensioner and move the tensioner off the
    serpentine belt with the serpentine belt tool. Slip the belt off the tensioner
    pulley with your other hand and then slowly move the tensioner back to its normal
    position. You can pinpoint the location of the belt tensioner by following the belt
    routing diagram, printed on the fan shroud.
  2. Disconnect the negative battery cable from the battery with the battery wrench.
    Push the cable end away from the battery so it doesn't make contact during the
    repair.
  3. Turn the lug nuts on the right-front wheel counterclockwise until they're loose
    enough for hand removal, but leave them on for now.
  4. Lift the right-front end with the floor jack and support it on a jack stand placed
    underneath the right-front frame. Remove the lug nuts and right-front wheel by hand
    and set them aside.
  5. Slip the serpentine belt off the alternator pulley by hand. You can access the
    alternator through the wheel well. Unplug the wiring harness from the alternator
    by hand and remove the ground strap with your socket set.
  6. Remove the alternator mounting bolts with your socket set. Lift the alternator out
    of the engine well, through the wheel well. Insert the new alternator in reverse of
    how you removed the old one.
  7. Thread the alternator mounting bolt through the new alternator and into the
    alternator bracket by hand. Tighten the bolts with your socket set.
  8. Attach the alternator ground strap with your socket set. Plug the alternator
    wiring harness in by hand.
  9. Slip the serpentine belt over the new alternator pulley. Reinstall the wheel and
    lug nuts by hand. Lower the Taurus of the jack stand with the floor jack.
  10. Move the belt tensioner aside again and place the belt on the tensioner pulley with
    your free hand. Hold the belt on the pulley and slowly move the tensioner back to
    its normal position. Reconnect the negative battery cable to the battery.
Hope this helps you.
Take care and good luck

Things You'll Need:
  • Battery terminal wrench
  • Serpentine belt removal tool
  • 3/8-inch ratchet

  2. Remove the serpentine belt by inserting the end of the serpentine belt tool into the square hole on the belt tensioner and rotating the removal tool clockwise. Unplug the alternator's electrical connector. Remove the bolt holding the positive voltage cable to the alternator using a 3/8-inch ratchet and a metric socket. Remove the positive voltage cable from the alternator.

  3. Remove the alternator bracket bolts using a metric socket connected to a 3/8-inch ratchet. Remove the alternator from the car. Place the new alternator in the mounting brackets and reinstall the mounting bolts using a 3/8-inch ratchet connected to a metric socket.

  4. Reinstall the positive voltage cable on the alternator and tighten the retaining nut using a 3/8-inch ratchet and a metric socket. Plug in the alternator's electrical connector.

While driving my 2003 Jetta TDI last night accelerating up a hill my battery light came on and the car died. All other lights work, glow plug light still comes on. Engine turns over but does not fire. ...


Did you check the battery? Alternator? The 2003 Jetta TDI's are FAMOUS for breaking the alternator pulley right off the shaft. Is your serpentine belt hanging?
You could have a bad battery, broken alternator, broken serpentine belt, or bad alternator among a few other things. If your belt is hanging either the belt broke or more commonly, the alternator puller broke off the shaft.
It happens all the time with the 2003's

Dim battery light on dash when i'm driving.


Battery doesnot get charge due to dead alternator or loose serpentine belt. If you in US go to nearest Autozone store and check the battery for volatge and alternator for charge. If both fine check the serpentine belt if it is tight enough
http://www.ehow.com/how_2279100_check-serpentine-belt.html?ref=fuel&utm_source=yahoo&utm_medium=ssp&utm_campaign=yssp_art
If it is fine check the connections of alternator and battery for corrosion. Corrosion can increase the resistance and decrease the electrical current
Please kindly let me know if you need more info
Good Luck

1997 nissan sentra serpentine belt


The serpentine belt has nothing to do with the brakes. It does have something to do with the alternator which charges the battery. the burning smell is probably the result of wasted grooves on the underside of the belt. it is the belt you see just inside the car engine compartment that turns the AC unit compressor pully , the alternator, etc.it is connected to the crankshaft pully.. If you have a front wheel drive it is located on the side of the engine compartment.
