Assuming you did all of that right, have you jumped the starter? Plus, maybe I'm not understanding this question right, but why did you swap the radio for a no start condition?
Where is the alternator on a VR Commodore?
its sbove the head on the left hand side when u look at it its round and has belt on it. you need to take the tensioner off its black and belowe the altenator there are three bolts and a nut which holds the cable that charges the alternator from the battery.
What kind of rotor is most suitable for turbo alternators which are designed to run at high speed?

Does the cam belt also run the alternator on a clio 1.5 dci 2001?
No, the timing belt is under a cover and you'll probably never see it unless you remove a lot of peripheral covers and other hardware. The alternator is run by a serpentine belt.
Your ford probe charging meter shows no charge and runs the battery down?
Why Batteries "Die"
There could be many causes, but the most common causes include:
- Corrosion on the battery terminals and/or the battery cable terminal connector clamps which inhibits or totally blocks the flow of charging current.
- A charging system which is out of adjustment or defective [loose drive belt (s), defective alternator or generator, defective voltage regulator, damaged wiring, disconnected, loose, or corroded connectors and/or grounds, etc.].
- Battery is just plain "worn out"; has reached the end of it life span.
How do you fix car alternator?
IF you have to ask this question, then the answer has to be, "You can't fix it.!" Modern alternators are precision electromechanical devices, which require specialized tools, test equipment, and knowledge in order to repair [actually, while opened up, it is best to do a total rebuild]. It would be much easier, and probably much less expensive, to simply trade in your old alternator on a remanufactured one. A word of caution, alternators are expensive, and you should be certain that it is defective BEFORE you replace or attempt to repair it. I cannot even begin to recall the number of people [including me] who replaced a suspected defective [but perfectly good] alternator only to find out that something else was the cause of the failure to charge problem. Go to a major chain auto parts store and have your charging system and battery tested [all done simultaneously] usually for FREE. Make sure the alternator is truly defective before replacing or attempting repair.
What loud sound? What does changing these items have to do with the transmission. You need to provide way more information.
Answeri know whaT mean i have a 87 s 10 w 2 8 v 6 Lou sounds like a jet engine or somrthing fan clutch and all that good that was 100000 miles ago now have almost 300,000 on truck don't worry about it if the truck moves and runs without overheatin than don't worry about itMy 1995 s10 has always had a roar when I drive it cold, only for a moment though. I have heard this in other chevys too. 13 years old now with 108k miles, it's ok.
How do you replace the alternator on a Ford Windstar?
It will be usually near the top of the serpentine belt routing. It will be connected to a pulley that belt goes around this pulley. It will have a ground wire along with a connector. It will have several bolts mounting it to the mount that it is on. It will also have on it vent looking openings. If you look in them you will see copper wire coilings. It is sort of cylinder shaped, but lying long ways. I hope I explained this good.
Testing An AlternatorMany auto parts stores will offer free alternator testing, either on the car, or off.
Testing method:
- Start the engine and allow it to reach operating temperature
- Connect a voltmeter between the positive and negative terminals of the battery
- Voltage should be 14.1-14.7 volts
- If voltage is higher or lower than specification, connect a voltmeter between the battery positive (B+) voltage output terminal of the alternator and a good engine ground
- Voltage should be 14.1-14.7 volts
- If voltage is still out of specification, a problem exists in the alternator or voltage regulator
- If voltage is now within specification, a problem exists in the wiring to the battery or in the battery itself.
Before starting, make sure you have the belt routing diagram - likely inside the engine compartment somewhere, draw your own, or download one.
The belt tension is not adjustable - the belt tensioner takes care of that. If the belt is loose, the tensioner will have to be replaced.
See "Related Questions" below for more about the serpentine belt.
Replacement Procedures - 3.0l Engine- Disconnect the negative battery cable
- Disconnect the wire from the terminal - 5/16ths (?)
- Disconnect remaining wiring connector(s)
- Detach the serpentine drive belt- if all you're doing is the alternator, you might try putting a piece of tape on the belt as it crossed the various pulleys to hold it in place.
- Loosen the large, horizontal oriented pivot bolt - goes through the top of the power steering bracket
- Remove the alternator bracket / brace - 2 bolts & one at the back of the alternator - set it aside for now
- Now you can remove the pivot bolt
- Remove the alternator- may have to pry it / weasel it out of the mounting
To install:
- Position the alternator on the engine
- Install the alternator pivot bolt and bracket / brace
- Tighten the:
* alternator brace to 15-22 ft lbs
* pivot bolt to 30-41 ft lbs
- Install the serpentine belt
- Re-connect the 2 wiring harnesses, and the wire held on with the nut
- Connect the negative battery cable
Changing the alternator on the 3.8 is very easy. There are only 3 bolts holding it on. There is 1 wiring plug and 1 battery / hot wire connected to it.
- Disconnect the positive cable from the battery as to avoid any electrical shorting,this will clear any codes and the check engine light if it was on.
- Remove the nut from the single wire on top of the alternator. Screw the nut back on so you don't loose it.
- For the wiring plug, just push in on the drivers side of it and pull up and it will come off.
- Remove the belt - grab the backside of the belt the runs from the top of the alternator towards the back of the van, pull real hard on it towards the front of the van, (be careful not to pinch your fingers between the belt and the pulley) and the tensioner will give allowing you enough room to slide the belt off of the alternator.
See "Related Questions" below for more about the serpentine belt
- Then remove the 3 mounting bolts and voila - it's off!
- Start with remounting the alternator with the 3 bolts
- Hook up your wire - using that nut you did not loose - and wiring plug
- Re-install serpentine belt - make sure the belt is around all of the pulleys and lined up correctly and pull again towards the front of the van to slide it back on - again...be careful not to pinch your fingers between the belt and the pulley!
- Hook the positive wire back up to the battery and then have an assistant to just bump "NOT START" the engine as to get the belts properly aligned.
- Take a visual inspection and make sure the belts are positioned correctly on the pulleys and then go ahead and start the van.
Good luck!
To remove the alternator on a 1998 ford Windstar if it is a 3.8L engine: FIRST - Remember to disconnect the battery!! Then, remove the tension on the belt. There is a tensioner towards the rear of the engine. Use a good box wrench and pull as much as you can because the tension is hard on those engines. Once you have that off, remove the 3 bolts and they just have to be taken off after that you have to remove the ground. Make sure that it is clean. When reinstalling, put some die electric grease on it. There is 1 electrical connector; unplug it. Also put on reassembly die electric grease in there for better conductivity. You should have the alternator off...just do the reverse to put in the new one.
If the 96 is like the 98, loosen the mounting bracket bolts, make sure you remember which way the serpentine belt goes on, pull off the belt, remove alternator, replace with new one, put belt on, use a pry bar to re-tighten the alternator and tighten bolts.
It was about the easiest thing I have done on my '96 with a 3.8L engine. First always disconnect the battery when removing charging system components for safety. Rather than loosen the tensioner, I was able to grab the serpentine belt past the alternator with my hand and pull against the tensioner to gain enough slack to slip the belt from the alternator pulley with my other hand (careful don't get pinched) . Next remove the cables and electrical connectors. Now you can remove the mounting bolts and remove the alternator. Compare the replacement alternator to the one you removed to insure they are similar enough to install the new alternator. Reverse the process above... Install mounting bolts and torque appropriately, connect cables and connectors, route the serpentine belt, pull slack on the belt and slip it over the alternator pulley, reconnect the battery and check for proper operation. Even with the trip to the parts store, it probably took me less than an hour.
It is not hard to do...the alternator is right on top. Just take the serpentine belt off, remove the bolts and plugs, and bolt the new one in. be careful not to torque the top screw too much or it will break off.
Disconnect the batter cables so you, and car don't get a shock. remove the 2 wire connected to the alternator. One is a Plug, push in on the l/s of the clip and lift up. The other one is held on my a small nut on a stud, Once this is done take a picture of write down the routing of the Serpentine belt, so you know that will be correct when your finished. There are just 3 bolts, loosen them all together. Before you remove the bolts even though they are loose, pull towards you really hard on the belt and pull it off the pulley. Remove the 3 bolts, remove the alternator, replace alternator, tighten 3 bolts, then pull on the belt again and put back on in same orientation, reconnect wire to alternator, reconnect battery, start engine
I just did it. It took about an hour. The instructions to replace a 2000 Windstar's alternator work for the 2002. See: How do you replace the alternator on a 2000 Ford Windstar.
I found that wearing an old work glove made it much easier to pull the belt against the tensioner. Also, when you replace the belt, make certain that the belt is inside the grooves of each of the pulleys. It was off the first time I replaced it. Don't bother trying to push it back; take it off the alternator again and re-thread it.
Once I finished, I started the engine and noticed some whining from the belt. I also noticed that it rode a bit outside of the polished spot on the pulley immediately below which rides on the outside of the belt. I double-checked all the pulleys again, and they were all on. After driving the van the couple of miles to the auto parts store to return the core, it quieted down.
First you disconnect the battery. then you need to take the belt off by the back pulley. But you don't need to take it all the way off. Just so you get the alternator belt off. I just replaced the one on my 1997 . then you have three bolts, and one small nut to remove . Then put all back together the way you took them off. Jon
you have to remove belt and disconect neg battery cable 3 15 mm bolts hold alt on,1 plug then pos.
You must have the car well off the ground because the best way to get to it is from the back of the engine. There's a nut back there that's hidden. Might as well change the rear spark plugs while your there. To change the number 6 you have to remove the alt. bracket anyway.
Removing the belt and alternator and replacing the new one is just as stated above, but putting the belt back on isn't such an easy task on my 2000 windstar. It is very difficult to pull back on the belt to replace it back on the pulley. It takes a fair amount of pulling and when you pull on the belt all the pulleys move so you can't easily place it over the alternator pulley. To remedy this jack the car up on the front passenger side and remove the front passenger side wheel. Then securely place jackstands under the van so that you can easily slide under the car. Locate the belt tensioner which is the small pulley closest to the rear of the van. Call a buddy to help at this point. Have the buddy stand by at the topside of the the van. Place a 13 MM boxend wrench on the retaining bolt for the Belt Tensioner Pulley. Push the wrench toward the front of the van as if trying to remove the bolt (counter-clockwise motion) Push it as far as you can. While you are holding the tensioner have your buddy slip the belt back over the alternator pulley. Once this is done slowly release the tension on the tensioner. Replace the wheel, lower the car and give your buddy a cold drink!
Perfect tool to release the ford windstar 2003 belt tensioner:socket wrench breaker bar, 1/2", remove the head (don't know the
name), Normally you can get those socket wrench breaker bar from 15 to
18 inches, I guess. If the bar is too long, you may remove air
conditioner part (don't know how to say the name, you will know what I
am taking about when you get there, )
How do you replace the alternator in a 1989 Acura Legend?
Simple... See how and where the old one is and put it the same way... All you have to do is loosen the belt by loosening the belt tensioner. Then unplug the cable, remove the bolts that hold the alternator. Replace it with the new one, plug it in, put the belt on and tighten the tensioner to give the belt "tension" obviously. and Presto
What is vehicle doing??
With a fully charged battery
Check voltage with a volt meter at battery at rest it should be around 12.75
With engine running volts should be 13.8-14.2 if in this range alternator is working
Check battery cables for looseness and/or corrosion
make sure that the current its getting to the starter solenoid i had a problem when i tried to start my car and the problem was the back part of the ignition switch it had a loose screw i fixed it and now it starts fine
How do you change the alternator on a 2001 Honda civic ex?
Let me tell you it is not fun.... First you hace to remove the power steering pump. That is held on by 2 bolts. After the the power steering pump is off to the side you have to remove the 2 electrical clips on the alternator. The wire on the left side is held on by a nut, and the one on the right is held in by a "squeeze" clip. Next loosen the 2 bolts and the tensioner on the alternator and insert the new one. Have fun because unless you have tiny hands it is a pain in the butt. put everything back to get...and hope you put on enough tension or your car will squeel like a banshee. I hope this gives you a little insight.
How do you remove the alternator in a Toyota Corolla?
first remove the batttery connections. second remove the belt that goes around it either by the tensioner if serpentine or if v-belt. the alternator i think on that car is underneath the passenger side of the wheel well. remove if there the dust cover. there is 2 bolts that hold it on the mount less than 6 inches apart ( top and botton) remove the positive connection and the plug. to put back on reverse the procedure.

What is rotor in ac alternator?
A Rotor is a mechanism in the alternator that is driven by the pulley belt from the engine.which creates a magnetic field which causes voltage.
Answer.
The rotor does not 'create' a magnetic field. The emf induced in the stator winding is due to the residual magnetic flux of the rotor which cuts the stator windings as the rotor rotates.

How do you remove serpentine belt from alternator on 1995 Chevy s10?
Get a ratchet with a 3/8" drive. You may need a short piece of pipe for leverage. You could use a 1/2" drive (bigger wrench) with a reducer on it. Or even a breaker bar with a reducer on it, as long as it is 3/8" at the end. Crawl under the truck. On the lower passenger side you will see the belt tensioner pulley. In the arm, between the pulley and its pivot, you will see a 3/8" square hole. Put the wrench in it. With the wrench set correctly, lift the tensioner and slip the belt off of a pulley.

How do you install an alternator belt on a 1993 Ford Festiva?
First of all, you'll want to remove the old belt. This can be done by loosening the adjustment bolt on the alternator bracket. On my alternator (I have a '93 Festiva but an '88 alternator--not sure why) I have only 2 bolts that hold my alternator in place: the pivot bolt below and the adjustment bolt above.
You'll see that the adjustment bolt is located on an adjustable bracket: once the adjustment bolt is loosened slightly, you'll be able to pivot the alternator forwards and backwards.
After loosening the adjustment bolt, pivot the alternator to decrease tension on the belt. Remove the belt, keeping in mind which pulleys it was connected to, so that you can properly install the new belt.
I just did this today on my car, and I used a V-style belt. Your local auto parts store should be able to find the right part though. Make sure that you take your old belt with you to the store so that the new belt is exactly the same size.
Install the new belt. On my car, there were 3 pulleys to hook it around, including the one on the alternator. Pivot the alternator to increase tension on the belt until you feel a fair amount of resistance, then tighten the adjustment bolt.
Now to check belt deflection. This is a test of whether you got the belt to the correct tightness. Get out your 6 inch cheap-o plastic ruler. Find a spot directly halfway between two of the pulleys and push on the belt. You should be able to push the belt "in" 0.5 inch. Belt deflection on certain cars varies, but I've been seeing 0.5 inches on every place I look.
With that, you should be done changing out the belt. Hopefully this helps at least a little. I've been working on my alternator today, so all of this is fresh in my mind. I still need to check my belt deflection because I don't know where my girlfriend keeps her rulers. Haha.

How do you deactivate the alarm in a 94 Tempo?
Sadly, the Tempo never came equipped with a factory alarm system, the system in your '94 has to be an aftermarket setup. If you want to keep it, go to a local car alarm store or a place that specializes in them and ask them to either remove it for you, deactivate the alarm, or purchase a new remote or 2. The true answer you're looking for would lie in the manual booklet for the alarm itself.
How do you change alternator in 1989 Honda accord lxi?
Mine went out this month, the only real way was for my mechanic to "drop the axle, to get to the alternator from the bottom".
Above is not entirely true.
Here is a 1/2hr removal procedure. It is very simple, dont be intimidated.
Did it on my nephews 89 accord
From Top
Remove battery Ground
Remove top alternator nut/adjusting screw mechanism
From Bottom
Remove bottom hanger bolt
THEN remove bottom bracket (2 bolts)
Spin alternator around and remove plug and wiring
Now at this point the only thing that wont allow the alternator to fall through of course
is the axle. Look at the engine block just in front of the bottom bracket you just removed. There is an engine assembly hole casting. This loop casting that protrudes out is ONLY used to install the engine. A 4" grinder quickly slices this cast iron loop off.
The Alternator will fall through with a little wiggling...worked awesome.
DONT USE A HAMMER TO BREAK OFF THAT LOOP ...YOU MAY BREAK TO FAR...LOTS OF ROOM>>> GRIND IT.
