What causes the generator to burn out after replacing the alternator
Vw electrical systems are fragile to begin with!! Better to dismantle it and do it right than take a chance... good luck:)
How do you replace alternator cummins?
Disconnect the battery, remove all wires from the alternator, slacken the belt tensioner, slip the belt off of the alternator pulley, unbolt the alternator, and remove the alternator. Installation is the opposite of removal.
How do you replace the alternator on a 2000 Mercury Cougar?
It depends which engine you have 4yl zetec or the 6 duratec i have done it on the v6 a couple of times its averages me about 4.5 hours on the ground and the car jack. here is the online manual on how to do it on 4 cyl or a 6 cyl. All you need is a ratchet set, flat head screw driver, breaker bar to remove wheel nut. its pretty straight forward if you have the patience. be careful tightening bolts and nuts. i broke the tie rods as i was tightening the bolt was pretty brittle.

Replacing an alternator on a 2002 Chevy S-10 or Blazer is some what easy Disconnect battery unplug harness on alternator loosen Serpentine belt if you are careful you can keep the belt on all the Pulleys remove the 2 bolts holding on the alternator and gently use a pry bar to remove alternator use two wrenches to remove positive lead wire place new alternator in position may require light tap with rubber mallet reinstall bolts and both wires and put serpentine belt back on and reconnect battery.
Just be careful when disconnecting and reconnecting the battery. To prevent a potentially dangerous short and/or explosion, disconnect negative first, and reconnect it last.
Where is the alternator located on a 1995 Dodge Neon?
the alternator is tough to find on the dodge neon. this is because the engine compartment is so compact. If you want to find the alternator, first you have to know what it looks like. If you need to, find a picture of one on the internet. Then open the hood of the neon.Look at the engine. Look at the left side where the coolent pressure cap is. Look below that...in that general area you will see the alternator..it is hooked up to a belt. If you can find the belts you can find the alternator. If you still cant find it, post again.
Answeris is hard to find and tight if your just accessing it the best way is to jack the vehical up support with jack stands, from under the car you can easly follow the wires to the alternator. If you changing it that's a bit more work feel free to e-mail if you need more help.ANSWER-- The Alternator is on the passenger side between the engine and firewall. You must jack the car up to do anything to it. To change it try to get a copy of the remove and replace diagram from a local dealer - they will most likely give u a copy of their blow apart.
Where is the alternator located on a Saturn SL?
Altenator is located on the back bottom side if the engine below the power steering pump. To remove it you will need to take of the front passenger wheel and remove the splash shields. Two bolts hold it on. It will take some twisting, bi=ut that is the way the factory manual tells you to take it out.
Unless the battery is shorted or sulfated and will not take or hold a charge, most likely the alternator is bad
Check the transmission neutral switch or the connection to it. The neutral switch is on the lower left side, beside the kickdown rod. There is also a connector in the wiring harness on the right side of the engine, at the rear of the right side valve cover. If the neutral switch isn't functioning for any reason, the symptoms will be exactly what you described. I once did some engine work on my 88 Maxi and forgot to connect the neutral switch in the harness, so I speak from sad experience...;-)
What if your 1998 peterbilt is burning up alternators?
Make sure the alternators are properly installed and aligned.
How can a new battery still go flat with new alternator installed?
If you install a new battery & new alternator and the battery runs down overnight then you have something pulling power from the battery. Look for any light on the vehicle that is on or a relay that is stuck.
The reason is that sometimes a car battery does not have enough charge inside it to start the engine BUT it often will have enough charge in it to keep the engine running after it has been started by "bump-starting" or "push-starting" the car.
But an auto gearbox does not work like a manual gearbox -
it is impossible to bump-start or push-start a car that has an automatic gearbox!
The only way to start a car engine which has an automatic gearbox is to use a good battery to start the engine.
If your car's alternator is not working you could re-charge your car's battery and then it would start the engine ok, even if the car was an automatic.
Here is what you do:
* first disconnect just the +" lead, or both leads, from the car's electrics * then use a household AC battery charger to charge it up * when it is re-charged you can re-connect the battery to the car's electrics and
* it should start the car ok
Another way to get the engine to start is to use a pair of jump-start leads from a good battery in another car.
To avoid burning cables or even a dangerous car fire
Make SURE you ONLY ever connect
"+" to "+"and "-" to "-"
that is
RED TO RED and BLACK TO BLACK
!!!
And it is a very good idea to keep the other car's engine running all the time, to be sure its alternator keeps its own battery charged up!
But the main problem for you will still be this: if your car's alternator is not working, your battery will keep running down fast whilst you are driving the car.
So it a good idea to get that alternator fixed as soon as possible, otherwise you'll be looking for someone to help you use those jumper start leads every time you have to stop the engine of your car!
As you said in your question, if the alternator is not working, so the battery is not being charged, it is a very good idea to take the positive cable off the battery every time you stop the engine. Doing that every time you stop will prevent the car's other electrics (security alarm, dashboard clock, etc.) from running down the battery whilst you are parked. The longer you are parked the more current will be drained from the battery.
So, if you are not able to re-charge the car's battery somewhere by using a household AC battery charger, always disconnect it from the car's electrics until you get the alternator fixed and your battery is fully charged again.
How do you replace the alternator on a 1998 Honda Civic?
i replaced mine twice, you can bring it out through the top end of the car but get it has a bolt from underneath the car, you need to take off the intake (plastic part) as well as the brake cylinder, as it is a tight fit, however it only comes up out of the engine and cannot be removed from the bottom, don't forget to disconnect battery before working on the car.
Actually this is not completely true. It is very possible to remove the alternator from the bottom of a 1998 Honda Civic. In order to replace the alternator you must remove the plastic air hose and air filter box (make sure to stuff the throttle body assembly with a clean rag). Next remove those brackets that are in your way holding the electrical connections near the alternator so that you can get your hands in there. After this is done you are ready to start removing the alternator first remove the top two bolts holding the alternator and the adjusting mount, and remove the negative connection to the alternator. Then jack the car up and remove the driver side tire (this will give you access to the lower mounting bolt). Next get under the car (after securely raising your Honda) and remove the small screw from behind the alternator. Then remove the lower alternator bolt, alternator with a long screw driver (to pry it out) and move the belt. Then remove the alternator mount (there are 2 bolts there). This is the tricky part turn the wheel all the way to the driver side. Then get the plastic molding covering the drive belts out of the way and start lowering the alternator so that you can make it side in to the opening the turn it until you get it out.**** To install do the reverse but make sure (*****) to push or pull (how ever it will work for you) the spacer on the mount, so that the inside of the mount where the alternator will go is flush (?? this is key).

More than one way to skin a cat
----------------------------------------
1) I took of the neg connect on the battery.
2) Put the car on jack stands and removed the drivers side tire
3) Removed the five or six 10mm bolts that hold the plastic air duct in place.
4) Pulled the air duct or whatever you want to call it out. Make sure to put this back in, the car will be noisy and may not cool as well without this part.
5) Removed the wires from the alternator.
6) Took out the two bolts holding the alternator in
7) Removed the two bolts holding the mount bracket in.
8) The Alternator was loose but could not be removed.
The wheel and the drive shaft were not a problem for me but the alternator would not fit between the engine and the frame.
9) I put my floor jack (with some wood) under a solid lift point on the engine and jacked the engine up about ½ of an inch. This made enough room to remove the alternator.
Slipped the new one in and did the above steps in reverse. This car has about 210,000 miles. Not bad for an alternator, not bad at all.
The cost: Two pieces of pizza, four bud lights, one broken finger nail and about 60 minutes. Oh and $130 for the new alternator.
THIS IS HOW I DID IT
This is a general overview of how I replaced the alternator in my 1997 civic LX. Disconnect the negative terminal from the battery. Jack the car up, position your jack stands, remove the driver's side tire. Remove the two bolts from the top of the alternator (12mm & 14mm). Unplug the green connector from the back of the alternator. Remove the terminal wire (the one protected by a black rubber boot) which is held on by a nut.
From the bottom, remove the small bracket (used to keep wiring in place) connected to the alternator by a screw or small bolt. Remove the long slide bolt from the alternator (14mm I believe). The alternator should now be free, from the bottom, push it out of its bracket and position it out of the way. You'll now need to remove that bracket that held the alternator in place (14mm I believe).
Remove the car's oil filter. You'll now be able to slide the alternator out from the bottom. It's a tight fit but it should come out. Before installing the bracket back in the car, make sure the new alternator fits inside of it. The new alternator may not fit and you'll have to adjust the spacers. I used a hammer to do this.
Repeat the process to install the new alternator. To tighten the belt, you'll be using the top 12mm bolt. Using a long tool or crow bar, you can push the alternator towards the fire wall, once you have the correct tightness of the belt, fully tighten the top 12mm bolt. Before starting the car, replace the oil filter and add oil if needed!
Word of caution, I tried two different "remanufactured" alternators from the big car parts store down the street. Both were bad, do yourself a favor, and don't get a remanufactured alternator! Spend the extra money and get a new one, I got mine from KOI/Savage. Best of luck!
When cold, the alternator produces more electrical energy to recharge the battery. After things warm up a little, the electrical energy drops back to maintenance mode, producing enough energy to operate all of your electrical component and maintain the charge level of the battery. At that point you'll see a drop on the gauge. Also, any device which turns on suddenly will cause the voltage level to drop briefly. It's normal and unless you are unable to start the vehicle in the morning or see the gauge in the red area, or the yellow area for an extended period, you're probably ok.
How do you replace alternator located on a 1999 Pontiac grand am se?
alternator on a 2000 Pontiac runs off a serpentine belt if its loose then chances are ur serpentine belt is worn or stretched or your tensioner pulley is bad or the tensioner itself..alternator bolts stable does not move like the old setup.
How do you replace alternator 1997 Saturn SC2?
Access to the alternator is much easier if you remove the passenger side mud shield. To do that, lift the front of the vehicle, put it on jack stands or some other secure and stable blocking. Remove the passenger side front wheel, then examine the mud shield and find the pins that hold it in place. Carefully remove the pins and work the mud shield out of the fender area.
With the mud shield removed you should be able to see the alternator and get to the other components at the head end of the engine.
Disconnect the negative terminal of the battery! If you work on the alternator with the battery connected, bad things will happen!
Release the serpentine belt tensioner.
Remove the bolts holding the alternator.
Carefully disconnect the electrical connections to the alternator and note which wire goes to which terminal on the alternator.
When replacing the alternator, just do everything in reverse order.
Where is fuse or relay on alternator wires 04 sprinter?
Only fuse would be in the PDC that bolts onto the positive battery cable.
Only fuse would be in the PDC that bolts onto the positive battery cable.
How do you know if you have bad alternator?
A simply check is to take a volt meter set to 20 volts DC and check the voltage at the battery posts with the engine running. It should read 13.5 − 16 volts. Any more or less and the alternator is defective.
Where is the alternator fuse in a 2000 Toyota Echo?
It's in the red cover that is connected to the positive terminal of the battery
What is the purpose of a diode in an alternator?
The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. The alternator's charging output flows through six diodes in the rectifier assembly before it goes to the battery and electrical system.
