Alternators

With a few hundred different ones for different applications pick a price. You need to state the year make model and engine size.

if it is a 2.5 v6 than take the passenger front tire off and the alternator is right behind the plastic shroud

14.3 to 14.6v dc

You don't. Disconnecting a battery cable to "check" the alternator is not a good idea. The removal of a cable with the engine running cuases a voltage spike that can damage the computer system on the car. The proper way to check the alternator is with a volt meter.

If it has an external regulator. The orange wire comes out of the alternator, then is spiced-"T"- into another wire which still should be orange going to the regulator plug, and the other wire coming from the "T" should be an orange wire with a tracer that goes to the "no charge" light on the dash. The other wire coming from the light goes to the ignition switch.

The best thing to do is to drive it to the nearest auto parts store where they will check your charging system for free. You can check the output voltage yourself with a digital volt meter set to the DC 20 volt scale. With the engine running connect the red test lead to the red positive post of the battery and the black test lead to the black negative battery post. You should have a reading of close to 13.5 to 15.5 volts if the alternator is putting out the correct voltage.

if it slips, then it does not charge the battery, and you might not make it home if you are driving home at night with the headlights on.

You can start your engine several times, but you can probably only drive for about 30 minutes. When this happens, GO TO A MECHANIC OR AUTHORIZED DEALER RIGHT AWAY (or call roadside assistance)!

NOTE THESE ARE GREAT INSTRUCTIONS WITH A COUPLE OF IMPROVEMENTS: 1) VERY IMPORTANT TO DISCONNECT HOT LEAD ON CAR BATTERY BEFORE YOU BEGIN--I CAUSED A SHOWER OF SPARKS WHEN I ACCIDENTALLY GROUNDED OUT THE ALT WHEN TRYING TO LOOSEN THE BOLTS. 2) GET YOURSELF A MINI-RACHETT...OPEN END WRENCHES ARE TOO BIG TO GET INTO SOME OF THE TIGHT PLACES. 3) MOST IMPORTANTLY: YOU MUST JACK UP THE CAR ON THE DRIVERS SIDE WHEN TRYING TO REMOVE THE ALTERNATOR FROM THE ENGINE COMPARTMENT OTHERWISE THERE IS NO WAY YOU WILL HAVE ENOUGH ROOM TO GET IT OUT....VERY FRUSTRATING UNTIL YOU FIGURE THIS OUT...JACKING THE CAR UP DROPS THE AXLE a CRITICAL 2-3 INCHES. YOU WILL NOT HAVE TO DISCONNECT THE AXLE IF YOU DO THIS. I just finished installing a new alternator in my 1989 Honda Civic DX hatchback. The alternator was making a horrible shrieking/squealing noise. I used a piece of garden hose as a stethoscope to localize the sound. It was definitely coming from the alternator. Once I got the alternator off it was clear that something on the rotor had broken and was hitting something inside the alternator as it turned, scraping each time it hit. If something scrapes fast enough it sounds like a horribly loud squeal. The classic symptom of bearings failing is described as a growling. Mine was a squeal not a growl. Remove the alternator: Put the car up on ramps if possible to allow more room under the car. Unplug the wire bundle from the back of the alternator. Remove the 7 mm nut holding the wire to the top of the alternator. Loosen the nut on the pivot bolt at the bottom of the alternator (easier to access from under the car). Loosen the bolt at the top of the alternator. Rotate the alternator toward the front of the car and remove the belt from the alternator pulley. If the belt is worn consider replacing it. Completely remove the top bolt holding the alternator. If you want more room to work you can remove the upper mounting bracket from the engine (one bolt) that holds the top bolt of the alternator. Chock the rear wheels, engage the parking brake, turn the steering wheel all the way to the left. This moves the axle toward the rear of the car to give you more room to get the alternator out. Remove the plastic cowling that separates the left front wheel well from the engine compartment. You may want to take the left front tire off to get better access but I didn't find it necessary. Remove the nut from the bottom pivot bolt on the alternator and remove the pivot bolt. It's a tight fit, you might have to gently drive the pivot bolt out. The alternator is now disconnected. Push it up and toward the right side of the car to temporarily get it out of your way. Remove the lower pivot bolt bracket from the car's frame (two bolts). The alternator can now be worked toward the wheel through the open area in the wheel well and removed. In my case the new alternator came with a pulley installed. Do not remove the pulley from the old alternator. It's difficult, the nut is very tight, it's installed with both a lock washer and locking compound, and is not necessary unless your new alternator comes without a pulley. My new alternator warned that if I ever removed the pulley from the new alternator it would void the lifetime warranty on the alternator. Just be sure your new alternator has a pulley with the same diameter and rib arrangement as the old one. Both my old and new alternator were rated at 60 amps. Install the alternator: Reverse the process above. Work the alternator past the wheel. Install the lower pivot bolt bracket. Connect the wiring to the alternator (it's easier to connect before bolting the alternator into place). Insert the pivot bolt through the pivot bolt bracket and the alternator. It's a tight fit, you may have to gently tap it to get it to go all the way through. Hand-tighten the nut on the pivot bolt. Install the upper mounting bracket if you removed it. Put the belt over the pulley. Install the top alternator bolt and hand tighten the nut. Slide a crowbar between the engine block and the alternator housing. Gently pry the alternator away from the engine to tighten the belt. Tighten the upper nut on the alternator. The belt should be tight enough to give just slightly when pushed. Officially, "1/2 inch deflection when the belt is pushed with 20 lb pressure at the mid-point between the pulleys." Too tight will cause undue wear on the bearings. Too loose will cause slippage, squealing, and undue wear on the belt. Tighten the nut on the pivot bolt. Reinstall the plastic cowling between the tire and the engine compartment. Check to be sure all bolts are tight. After driving for a little while the belt may need to be re-tightened.

You have to be more specific....year... engine size... model... but basically around low one hundreds to do yourself... or the cost of alternator plus shop fees and labor... do online pricing ... instead of asking on line

if it has a delco alternator it is inside the alternator

the part alone can range from 160.00 to 350.00 it depends on what parts store u go to call around and find a store that price matches always get the lifetime warrenty (your gonna need it) the alternators for these cars go out about ever 12 to 18 months. the labor at a shope can go from 160.00 to 200.00 my sugestion is to buy the part on your own ( it cheaper then buying it from the repair shope) and have a pro install it doing it your self is very VERY difficult. all together your price range is gonna be about 400.00 or more.

Yes you can. I run three yellow tops in my show truck ( I need them to power 16 12" pioneer premier subs) and there is a trick you wont find in the website. If it is just a little low, charge it like normal. If you left your lights on or for any other reason, and the battery is completely dead and you are having trouble getting it to charge, hook it up to the charger and turn it to boost. You want it to send as many amps as possible to the battery. You leave it on boost for 2 to 3 hours, and the battery should be rejuvenated. This info came directly from optima customer service when I killed my 3 batteries.

Take a long extension. Usually two connected together and get the screw you can't find out from the back of the alt. This is only accomplished by taking the passenger tire off and reaching in there with the extension. Then skirt the alt. from the driver side of the car to the passenger side from behind the engine. It helps if you have two people. CIV --- In the 1991 CRX HF the best way is to unbolt the master cylinder. do NOT remove the brake lines! also, unplug the fuel line that is there and move it out of the way. unplug/move the wire harness that is there as well. pull the master cylinder a couple of inches out and a couple inches upward being careful not to move it too much as the brake lines are still attached! the alternator will come through the space that you've now created in front of the master cylinder. i tried the "passenger side of engine" method and don't see how that could work at all. other people say remove the axle. others say through the bottom or through the wheel well. on my 1991 CRX-HF the best way is the master cylinder method.

Sure you can. But it would be much easier to purchase a compacitor which acts like a battery in that it stores power and uses that to power what is connected to it. This also saves the alternator

Hey Ryan==Simply remove the neg battery cable then the ser belt then the wiring on the alternator then the bolts that hold it on. GoodluckJoe

on my 95 i took the driver side tire and brake assembly off to get to it on my 95 i took the driver side tire and brake assembly off to get to it

First find your tensioner pulley( it should be the one that is attached to an "arm"), it should be either a 3/8 or 1/2 inch drive ratchet to raise this. Next take your top two bolts out. Then, and this is the hard part, reach around the bottom of the alternator to the inside of it, you should find your third and final boltat the bottom of the alternotor. This bolt is extremely hard to get out but with a lot of patience and bashed knuckles your alternator should come right out. Just to add more detail to the above: 1. Disconnect the negative (black) cable from the battery. 8mm wrench works best. 2. Loosen and remove serpentine belt from alternator pulley. Use a 3/8" drive on the tensioner arm and pull counterclockwise to loosen. 3. Remove the top securing bolt from alternator/bracket assy. 13mm bolt. 4. Loosen, but do not remove top bracket assy arm. 13mm bolt on top of engine. 5. Remove nut from middle bracket assy. I suggest removing this small arm entirely to expedite removal of the alternator. 10mm nut on alternator stud and 13mm on engine stud. 6. Make sure all children are out of earshot for this step. You are now ready to remove the dreaded pivot bolt. 13mm bolt and a 15mm nut. Your best bet here is to get a box end wrench on the nut and a socket on the bolt. After you have recovered the wrench several times from dropping it and bandaging your hands from the numerous cuts you have sustained, remove the pivot bolt and fish out the 15mm nut you dropped. 7. Unplug the electrical connector and remove the power lead (13mm). 8. Remove alternator. 9. Remove bracket stud from old alternator and put it on the new one. 14mm 10. Install new alternator by reversing the above steps. This is really a 20 minute job that will turn into an hour long test of your patience. I want to personally thank the engineers at GM for making the pivot bolt nut almost inaccesable. It may actually be easier to disconnect the wishbones and rotate the engine. Maybe next time.

how do you replace an alternator on a 1990 integra

You don't need an alternator to start your engine only to recharge the battery. You could start any vehicle without an alternator but that doesn't mean it will run for long. Newer vehicles would just run till the battery was drained.

If the system is healthy, the voltmeter in the dash should read aprox 14 volts with vehicle running. The battery should be in good condition and fully charged (12.68 V) before you start it to get an accurate reading. If in doubt, take the vehicle to your local auto parts store and they will test the charging system for you for zip.
