How do you know if your starter went out or is it your alternator?
if it is your alternator your battery will be low or dead... your lights will be dim when turned on. , if you cannot crank your car or it will crank slowly it may be your starter or battery cable connection or a loose connection in the link........
, a low battery caused by an alternator will usually click rapidly the starter solenoid, when trying to start, and the lights will go out when cranking ..., for the most part turn on your headlights if they are dim the charging system or the battery is to blame .. hope this helps
Why do i have a Misfire after putting in new alternator?
Removal and replacement of an alternator should not causemisfiring of the engine.
Either this is a coincidence, OR whoever changed the alternator inadvertently damaged the ignition wiring system.
The "fix" for this problem is to have someone who knows what he/she is doing to fully troubleshoot the ignition system, identify the fault, and properly correct it.
How can you tell what Amp alternator is in a 1996 Tahoe?
I don't know where to tell, but replacement alternators range from 100-140 amps for that model year.
On the top & to the right of the alternator you will find some numbers look for 3 numbers followed by an A which stands for Amps such as 105 A. The numbers are usually hard to see, you can take a piece of white chalk & rub over them to get them to show up better.
i can't answer your question, but i bet i know who can. vfaq.com is a great source for info on dsm's ( diamond star motors )
Answer1.On any dsm the alternator is shot. Remanufactured alternators aren't always perfect.2.You removed the heat shields from the exhaust manifold
3. The gaskets between the head and ex. mani and/or ex. mani and turbo and/or turbo and O2 housing and/or O2 housing and downpipe are shot, replace them.
could be the immobilizer in trouble or might need to be reset especially if you had the battery out
How long does it take to install an alternator on a Ford Windstar 3.8?
It's pretty simple, actually. Search the web for a site with step-by-step instructions. There are several sites out there, so I won't repeat exact instructions here, but I've swapped alternators in mine several times now (175k miles and counting!)
The alternator is easy to access, at the top of the engine, in front, on the passenger side of the vehicle.
You pull the belt off the pulley - there's a spring loaded tensioner. You have to pull pretty hard, but you can get enough slack in the belt to just push it off the side of the pulley. Then you disconnect a few wires (I think there's one plug-in type and one that takes a 10mm socket to remove) both of which are pretty easy to get to.
Then there's two or three long bolts that anchor the alternator to the engine. These are pretty tight, so you might need a long handle on your wrench to get enough torque. I have a 3 foot long piece of 1 inch iron pipe that I can slide over the handle of my rachet wrench. That made short work of them.
Then reverse the process. First time I think it took me about 1 hour start to finish. Now that I've done it a few times I could probably do it in 20 minutes.

How do you replace the alternator on a 1991 Honda Civic Si?
to replace the alternator there is 2 bolts.. one that lets you adjust the belt to take it off and tighten it and one at the bottom of the alternator and it come right off. Now the hard part is removing it from the engine compartment. I removed the brake booster to gain enough room to remove the alternator from the top. remove the 2 bolts holdind it on to the firewall and gently pull it back, there is a shaft with a spring attached to it on the inside of the booster along with a rubber O-ring, KEEP ALL THESE PARTS TOGETHER and DO NOT remove the shaft and spring from the booster housing!! JUST PUSH THE BOOSTER ASSEMBLY GENTLY TO THE SIDE ENSURING YOU DON"T BEND OR BREAK THE BRAKE LINES!! Once you removed the booster you can now remove the alternator through the top. To install just go in reverse order. Make sure and re-attach all the hoses and electrical wiring that you removed. Caution: DO NOT overighten the nuts on the brake booster when re-installing!!!!!
There is an easier way:
'89 Civic si 3dr: Alternator removal
Note: if it's been a while, best to use 6 point sockets / wrenches on all
A tiny drop of penistraining oil on fasteners where steel meets alum helps
But DO NOT soak em! - probably would be better to just leave em dry
Jack up & remove LF wheel
Disconnect + battery cable (10mm)
Depress pry tab & disconnect larger round multi connector
Remove (10mm nut under boot) alternator + cable
Loosen top alt adjust bolt (12mm?)
Loosen (14mm) nut from lower alt sleeve bolt (easier from below)
Push alt toward timing cover & remove belt
Remove lower (14) nut & upper (12) bolt loosened above
Tap sleeve bolt (w/wood or plastic) thru & remove (other end welded square flange)
Wiggle and/or gently pry alt off (place on frame behind oil filt for now)
Can remove upper bracket (14mm) to get outaa way
Remove lower sleeve mount bracket (2X14mm)
Remove 3 plastic (Phillips) snap nuts from crank splash shield in front of LF axle
Pull shield down & leave hanging (leave 4th snap nut underneath in)
Can now slide alternator along frame and remove past crank pulley thru wheel well
Reasm notes: A little auntie seize lube on all (non electric) threads will go a long way next time you go to loosen ( if you have a car this old you probably already know this).
Square flange on lower sleeve bolt is not perfectly square, (rotate 90 deg. if necessary).
How do you know when the battery is dead?
A visual check shows an excess of white buildup between plates. This is lead sulphate. If it is touching both plates in a cell, that cell is dead. This reduces power from the entire battery and may render it useless for applications that need full 12V. If a battery does not retain charge despite long hours of charging, it is dead. The lead oxide paste may have flaked off or the lead plates may have corroded leading to non-retention of charge and a dead battery is the result. If charging does not raise battery voltage or show adequate current according to its Ah rating, the battery is dead. If it is dried up and left unused without recharging for a long time, the battery dies.
How do you replace the alternator on a 1984 Chevy Monte Carlo?
I can answer if the car is set up the same as a 1995 Z34. The alternator is hidden on the backside of the engine between the firewall and engine block. Some genius decided to put it there, and they even have a flexible duct hose to provide cooling air to the alternator.
It is necessary to remove the two large engine mount (rear) bolts and drop the engine down about 10". It pivots on the two front engine mount bolts, no need to remove them. Dropping the engine down is necessary to get the old alternator out, and the new one in. You also need to remove the front Right wheel/tire. Behind the tire is a plastic/rubber cover on the inside of the fenderwell that you must remove to get to the alternator mount bolts on the pulley side.
It takes about 4-5 hours to change the alternator. Our alternator has failed three times in 10 years. This poor installation job by the Chev engineers costs us two ways:
1) The alternator fails due to poor airflow.
2) It's a SOB to change.

I Suggest buying a Chiltons or Haynes repair manual, be cause the answer above is obviously not going to help you.

-------------------------
Actually, an 84 is a rwd model. The alternator should be on the front passenger side of the block. There are only a couple bolts holding it on. Unplug the wires that are plugged into the alt. The top bolt is an adjuster bolt. Undo that to take pressure off the belt. You may need to slide the alternator a bit on the adjusting mount/bar that the alt is bolted to on the top. Remove the belt, remembering how it is routed on all the pullys. Then remove the top bolt, and then remove the bottom bolt. There may be a spacer on the bottom bolt, so be aware that you don't drop it and remember its position for reinstallation. The alt should just come right out. The total time to replace should be only between 15 min to an hour, depending on the bolts being "stuck" or not. WD 40 may need to be used on them before and after removal.
I've owned an 80 Monte with a 400, and an 82 with a 350, and had 2-3 alternators fail between both cars, so I got kind of good at swapping them out.

Yes!
That is the most reasonable approach to alternator replacement on this generation of Taurus / Sable DOHC vehicles. (some months later...)
"Reasonable"?? What was I thinking??
It's the ONLY way to get it out! (doofus)
How expensive is an alternator for a 1987 Mazda b2200?
Between $55.00-$185.00 depending on what type of warranty goes with it. or whether reman or new. Good Luck..........
Where is the alternator located on a 1989 Mazda 626?
passenger side of engine, low, towards firewall seat. i just removed mine, but can't get it out of the engine cavity. may have to remove the tierod, maybe even axle>?
The alternator can be coaxed out from the top by moving a couple of hoses and the wire harness as far towards the driver side as you can. With just the right tilt--it will come out!
How do you replace the alternator on a 1984 Honda Accord?
This is a very difficult repair. The lower cross member must be removed. Raise the front of the car and put it on jack stands. Remove the left wheel of the car. Put a jack under a stable part of the engine that can hold the weight. Unbolt the left side engine bolts and lift the engine a few inches. Remove the alternator bolts and disconnect the wires. I have an '86 Accord that I had to replace it in so it should be the same steps. Good luck and I hope this helped. You might want to buy a Chilton manual also for reference. i did this job once by twisting and turning the alternator over towards the passenger side of the car behind the engine. it can be done! i wouldn't have believed it would work....but the car is running again today. easier than undoing large engine bolts... but not an easy job.
Will a diesel engine run with battery cable disconnected if the alternator is bad?
A vehicle may not run if the battery cables are disconnected with or without a bad alternator. The best way to test an alternator is by voltage output when applying a load.
Charging system drops at idle but charges up at high idle what could cause this?
That would be the alternator, voltage rgulator, or even a bad ground. Email MYCOMATT167@YAHOO.COM follow up
Where is the alternator for a 1998 Mazda 626?
The positive battery terminal cable will always run to the alternator- just follow it down.
The alternator is in the car for two purposes. One ... to charge the battery. Two ... to run anything and everything electrical within the car when it's running. So basically, the battery is only there to start the car and that's it, the alternator has nothing to do with the starting of the vehicle.
If the car won't start, it's probably NOT the alternator. It's a possible problem with the battery or within the starting system. It could be caused by something as simple as making sure the shifter is in the park position all the way. (automatic transmission only of course) If this is an automatic, you can also try placing the car in neutral but MAKE SURE YOU USE THE BRAKES OR PUT THE EMERGENCY BRAKE ON before and while starting it. If it starts in neutral but not in park, it's the neutral safety switch gone bad.
If the car is a manual, the clutch safety switch located (usually) above the clutch pedal may be the culprit.
Now ... there are many things in the starting system that can go wrong from a fuse, to a starter solenoid, a starter relay, the starter itself, the ignition switch, a bad connection somewhere, a broken wire or a security system within the car. There are other things that can go wrong, but without knowing the year make and model of the vehicle, this is the best I can do for ya. Good Luck!
Sounds Like You Have A Voltage Drain, That Is Something Is On Or Grounded In The Car. To Test This Buy A Test Light At Parts House. Rermove The Negetive Cable From Battery, Leaving The Positive Cable Attached To The Battery. Connect Test Light Between Negetive Cable And Negative Battery Terminal: If Light Comes On You Have Something On Or Grounded. Remove The Bulb From Hood Light First ( The On That Lights Up When You Open Engine Compartment--HOOD }. Turn Off Ignition When And If You Find The Problem The Light Will Go Out. This Is The Best Way To Find Your Problem. PLEASE NOTE ++++++++ If The Light Don`t Come On. Your Battery Is Probably Bad. In Fact Go Have The Battery Tested First !!!! Then Replace If It Is Weak Or Bad. If That Don`t Work Try The Things Above. HOPE THIS ISN`T TOO MANY THINGS. GOOD LUCK --Try look for a fuse. There should be a Fuse that connects the Battery to Alternator. It by be burn out
Will a dead alternator drain a battery?
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.
My s3 mini battery won't charge?
Your S3 mini battery won't charge because your charger is faulty or because your charging system is faulty.
How do you replace the alternator on a Ford Taurus show picture where is it location?
We cannot show pictures, however replacing the alternator on most models and years of Taurus is very easy. It is at top right of engine and even the belt tensioner is easy to access. If you are careful and don't totally remove the belt from the lower pulleys, the entire replacement of alternator can easily be done in less than an hour.

You need a new belt, it has nothing to do with the battery, but rather the new alternator. The belt is probably old, dry and cracked so it is slipping during the acceleration period due to the load from the engine.
