How do you install 88 Dodge Aries Alternator belt?
First you will want to loosen the alternator. To do this you will need to loosen the bolt holding adjustment bolt in place. This is right under the alternator. After loosening this bolt, you can use the adjusting bolt to loosen the alternator and the belt should slide right off. Then you can put on the new belt and tighten the alternator using the adjusting bolt. After the belt is to the proper tightness, tighten the bolt directly underneath the alternator to keep the belt tight and from becoming loose.
So many things could be wrong and cause it to not start, but from what you have provided the next step would be to trace the cables to the starter and see if they are corroded or broken, you didn't mention if the car was turning over or not, so I assume it isnt, so if the battery has power, and the alternator isn't the cause then you need to follow the power, it goes from the battery to the ignition, then to the starter, since we know the battery is good, check to see if power is getting to the starter, if not trace the problem in between those two points.
Why does your 01 Oldsmobile aurora keep burning up alternator?
It is obvious that you have a very serious defect in either the charging system, or the electrical system of your vehicle.
It appears that the problem is not with the alternators, but somewhere else in the charging or generic electrical systems.
Due to the high cost of alternators, and the labor to reinstall, I suggest that you take your vehicle to a bone fide auto repair shop and have a PROFESSIONAL auto electrical Technician hook up his computer diagnostic machine to your Olds and run a full diagnostic analysis of all electrical systems.
What would cause a engine to start knocking after the alternator go bad?
I'm wondering the same thing for my 98 mustang gt. My guess is that if your electrical system does not put out enough voltage under high demand AND when accelerating hard (or up hill), there might not be enough voltage a the Mass Air Meter (MAF) to sufficiently power it. If that's the case the MAF might underestimate the air flow to the engine, causing the ECM (engine computer) to command an insufficient pulse width to the fuel injectors, resulting in a lean condition. This lean air-to-fuel ratio would, in general, cause increased combution temperatures, which in turn can cause pre-ignition and engine "knock."
Anyway, that's my take on it. What's yours?
Can an overtightened alternator belt break?
Yes, and it can break and for sure will wear out the bearings in the alternator.
Describe isomorphic alternation of generation and heteromorphic alternation of generation?
similarities of heteromorphic and isomorphic generation
Did you install a new voltage regulator? Is the belt tight? Maybe the "computer brain" is weakening.
Answer
If you have installed a new alternator and new battery, check the harness/wiring that plugs into the alternator, it may be corroded/bad connection causing your battery to not be recharged at idle speed; voltage should stay between 12-14.5v range and steady (some momentary drop may occur after turning hi beam lights, etc but it should return to proper voltage after a few seconds), as for the regulator, on most cases it is inside the new alternator so no further adjusting may be required; also, make sure you get the right alternator for your focus-there's like 3 types, the wrong one will cause your dashboard alternator lamp to be lit at all times-replace with right one or higher output if got power windows,seats,etc.Good luck! Buena Suerte!
Trouble code P0573 means: Brake Switch No. 1 Stuck High/Off Should have no effect on the alternator.
How do you replace the alternator on a Skoda felicia 1998 and where do the wires go?
The alternator on my wife's Skoda Fellatio has just failed as well so I'm shopping round to order a new one.
Having had just a cursory look under the bonnet it all looks pretty straight-forward. There's a thin wire going to a plug that is, at a guess, the charging indicator. There's a thick wire that comes off of a stud and which goes directly to the positive side of the battery. This is presumably the main feed from the alternator. No other wires. Nice and simple.
Oh, and just three nuts/bolts holding the alternator in position. Should be a half-hour job to change one.

If its a diesel with power steering you are in for a shock, you need to take out the radiator to give clearance, take off the belt tensioner pulley wheel to withdraw one of the two bolts, (not three). The pulley bolt is left hand thread and is lifted clear to slacken the belt for removal by getting a spanner on it and lifting. Not as easy as it sounds, it has a strong spring and is a bit fiddly, once the belt is off you can then turn the bolt the other way to remove it and the pulley wheel. removing the left hand headlight helps a lot as you can work through the hole that is left. best to find a scrap yard that still lets you take bits off and do it there first on someone else's car. Its not as bad as it sounds but is not the twenty minute job I thought it would be. Good luck, Steve
If its a petrol with power steering and an MPI engine then you are in for an even bigger shock as I have only just discovered. Removing this type of alternator requires a special tool. Without the special tool IT CANNOT BE REMOVED.
The procedure is to undo the nut which holds the belt retentioning roller to the engine mounting. Sure, both upper and lower bolts can be removed however, without releasing the tension from the belt the alternator can neither be moved nor removed.
The problem exists due to the positioning of the alternator and the belt retentioning roller - there is only 1/2-inch clearance between the bolt-end of the roller and the wheel-arch.
The tool is not available for public use. I have spoken to Skoda who have confirmed this. Even if you could buy the tool it would cost somewhere between £40 - £70 (confirmed by Ashley Down Motors, Bristol, UK).
If you could get the car over to a garage who has the tool then you might be able to persuade them to undo the belt retentioning roller nut so that you can fit the alternator yourself on the roadside - although, they might not be happy about this so phone them first. It may also mean offering a token payment of say £10 or so.
Is there a special tool for tightening the alternator belt on a Dodge Neon?
NO WELD YOUR OWN,.. USE FLAT STOCK BENT TO THE RIGHT ANGLE AND WELD THE END OF A WRENCH TO IT AND NOW YOU HAVE A SPECIAL TOOL FOR THE JOB. ( KEEP IT IN THE TRUNK FOR THE MONKEY!) =Answer=!!!! there are two bolts to losen the alternator on the bottom bolt stick a flat tip (screw driver) underneath the bolt and pull the flat tip up and the alternator will rise if u can't put it in use a smaller one or pull up the alternator till u can put the flat tip in it always works for me on my Neon and other vehicals
Answer
Rear tension bolt
I used a 1/4" drive ratchet/socket. It would probably be easier if you had an offset head ratchet wrench, or bend one you have one already and are willing. Bottom pivot bolt/nut
I used a ratchet wrench in this location. made things very easy to get to.
This process is lengthly and will test your patience. Practice makes perfect tho.
How can i tell if alternator is not working on a 2002 ford focus?
Usually the appropriate warning light on the dash will come on if the alternator is not producing current. If you don't trust the warning light, take a volt/ohm meter and (making sure it is set on the DC reading scale) connect it across the output terminals of the alternator to determine if any current is being produced.
Is it common to have to replace both the battery and the alternator together?
It's not at all uncommon. A failing alternator can easily damage a battery.
This is done by manufacturers to reduce the amount of large, heavy wire in the run from the battery to a switch, and then from a switch to the high current using device.
They run a shorter heavy wire the shortest distance from the battery to the device, with a relay added in the circuit. They then run lighter control wire from the relay to a lighter/cheaper switch in the passenger compartment.
This serves two purposes:
- Saving of weight, reducing overall weight of the vehicle, and
- Reducing the amount of Copper wire, and thus material cost.
Where is the Alternator located on a 1999 Cadillac eldorado?
I have no idea about this specific car, but the alternator in general is an electrical generator which is driven off the engine's crankshaft. It will normally be at one end of the engine and driven by a belt - it is easily identified as it is about the size of a pineapple and is surrounded by coils of wire.
Charge the battery, start the car and check the battery with a volt meter. Should have over 14 volts, if only say 12.4 to 13, then change the alt. or check the wiring.
How do you replace the alternator Subaru Outback 1996?
I'm 99% positive that Subaru put the alternators in the same place on all their cars (engineconfiguration. I currently own three subarus: 94 legacy sedan, 96 legacy outback wagon and 09 impreza wrx sedan. All the alternators are in the same spot for all my cars. I'm pretty it's the same case for yours. I was able to remove and reinstall a new one on my 94 sedan in less than 20 minutes. I hope that this help. Here are the steps to removing and installing an alternator on a subaru.
1) Remove the negative battery cable using a 10mm socket or a 10mm wrench. Once the terminal is off tuck it to the side so it does not touch the negative terminal of the battery.
2) Remove the alternator pulley/fan belt cover. On the legacy sedans and outbacks the cover is metal and it covers the top of the fan belts. There are two 10mm bolts that hold this cover in place.
3) Look for a round plug (usually green on subarus) and unplug it from the alternator. Next pull the cap off of the red terminal on the alternator and use a 10mm socket to remove the nut. Once the nut is off pull the cable out from the terminal. The new alternator usually comes with this nut in place but I would still save it just to be safe.
4) Look for the two long bolts that hold the alternator to the brackets attached to the engine. One is to loosen the alternator from the belt (goes up and down). The other bolt holds the alternator in place at the other end. Both these bolts need to come off in order for the alternator to be pulled out.
5) Once the old one is out. Install the new one in reverse order.
Do i need a voltage regulator?
Whether you need a voltage regulator depends on your specific application. If you're using devices that require a stable voltage and your power supply fluctuates, a voltage regulator is essential to protect those devices. For projects with sensitive electronics or batteries, incorporating a voltage regulator ensures consistent performance and longevity. In contrast, if your power source is already stable and matches your device's requirements, a regulator may not be necessary.
How do you replace the alternator in a 1967 mustang?
Remove the belt from your 1967 Ford Mustang alternator. Disconnect the alternator wiring. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
Why does a battery light stay on even with a new battery and good alternator?
What is the chrage when the vehicle is on? It should be around 15-15.5v
Where in alternator located on 2001 Toyota Tundra?
For a V8 you will find it under the left side of the engine. It can only be found underneath the truck. There to many parts on top to find it looking above.
How do change the alternator on a 2000 Mercury Sable?
Unless you're comfortable taking apart a lot of stuff, bring it to the mechanic. If you have the dual overhead engine (which I am assuming), your alternator is located under the engine. Access can be found through the passenger side wheel well. You have to pull out the splash guard and do take out everything in the way. If it's located on top, simply disconnect your battery, take off the belt, disconnect the connectors, pull a few bolts... it's pretty self explanatory.
