How do you replace the alternator on a 1987 Honda Accord?
MARK THE POSITION OF YOUR ALTERNATOR ON THE MOUNT BEFORE YOU REMOVE IT!!! This makes it easy to reinstall the belt to the right tension.
It's pretty easy, put the car up on jack stands (I just drove my front driver's side wheel up onto the curb), DISCONNECT YOUR BATTERY, remove your 12mm bolts on the top of the alternator and the 14mm on the bottom. Remove the green wire plugin, pop the alternator out of its space and turn it so that you can remove the pos wire 10mm nut with a socket and a couple extensions on it. If you have the strange mount that uses a difficultly placed 12mm nut to tension the belt, use a 12mm stubby box wrench from below (reaching up past the cv axle) to loosen it. I couldn't figure out another way.
Now from passenger's side panel, look down the firewall midway and you'll see where the heater hoses go in. Just before that you'll see a blend/mixer mounted of the firewall. Remove that one 10mm bolt holding it down. Now you can pull the alternator out from underneath those hoses by carefully lifting up on them. I found it came out easiest with the pulley side towards the motor.
Put the new alternator in the reverse. Tension the belt to the marks you put on the mount and tighten her up. If you forgot to mark the belt or put a new one on, the alternator belt needs 1/4 inch of travel. Meaning if you push on it from below in between the alternator pulley and the crankshaft pulley, it should depress no more then 1/4 of an inch.
Now thank your lucky stars for whoever discovered this trick rather then pulling the cv axle.
I performed this operation about a year ago. I bought the Haines repair manual and went by those directions. The driver's side axle (left side in the USA) has to be disconnected from the transmission to create a clear access path to drop the alternator through. There is no other way to remove it. Note: The inner axle end only needs moving far enough to get the alternator past. The axle is very difficult to remove completely from the vehicle, so I left the outer end in the hub and the inner axle end held up with wire to prevent damage to the cv joint or rubber boot.i just took the top driver side motor mount off and used a floor jack and jacked the motor up far enough to slip the altinator out it wasnt easy but a lot better than pulling and axle
I just changed the alternator on my 1986 Honda Accord (carborated). I did not need to remove the axle like everyone says. Once the old one is disconnected, it can slip along the firewal on it can be pulled out on the passenger side once it is free of the speedometer cable. I did have to remove one bolt. My buddy says it was for a heat selector valve. Once that was out of the way, it slipped out and put the old one in. It really helped to have a second person though. The total repair time was about two hours. It was my first alternator change and a pleasant experience.
If its fuel injected you can remove the air cleaner housing and remove it from the top, if its carbureted you must remove the left axle. But if you are careful , you can unbolt the alternator then pry the axle forward just a little bit so you dont have to remove the axle
On an 87 Accord with manual transmission (with carb.). You can remove the alternator by removing the hoses from the heater core on the firewall,remove the bolt that fastens the heat selector valve assemby to the firewall, pull the hoses and the assmbly out of your way, remove the air filter assembly from the carb. The alternator can then be worked out along the firewall on the passenger(right) side of the car. This is much easier than removing the drive axle. I don't know if this will work with automatic trans.
On an 86 Accord with automatic transmission, we just unbolted the alternator then worked it along the firewall, over to the passenger side of the engine. In order to do this we had to remove one bolt that holds the lower hose to heater core selecter. Then pull the hoses off and it came right out. It goes in the same way and we just had to replace the hoses we romoved because we had to cut them off. Very easy job and the hoses are not expensive. Taking the drive shaft off is bull crap. Its like a whole nother project and I would not recommend attempting to remove the drive shaft unless you absolutely have to. Came out beautiful!
.
The same thing can be accomplished on the 87 accord auto trans without removing the transaxle but you will have to remove the brake master cylinder. The alternator can be squeezed out the top this way but the bracket can not be attached to it or it will not fit through. There are also a few minor hoses and lines that will have to be undone and moved out of the way. The car I have is the LXI hatchback with a 12 valve engine that is super wide. On this car the around the back method would not work and removing the air cleaner still did not buy enough room because the manifold and the FI were in the way. Removing the master cylinder seemed a better option to me because I did not know how, or want to mess with the axle. This is a bad option however if you don't know how to bleed brakes.
How do you rebuild the alternator?
If you can get a rebuild kit for the alternator and have the necessary pullers and can solder in the diodes rebuilding is simply removal and replacement of the parts. I recommend you simply exchange the alternator for a rebuilt unit at your FLAPs (friendly local auto parts store) it is easier and cheaper in the long run.
Also there is a website that has a slew of alternator and starter instructions. They are called star-alt

When testing the 6-Pin PCIe connector with a multimeter what should the voltage read?
The 6pin PCIe connector supplies 12v DC on pins 1, 2(optional), and 3 (yellow wires). The other pins are ground.
How do you adjust the alternator belt on a Daewoo Lanos?
You cannot adjust the belt tension on the alternator, it is automatically adjusted by the automatic tensioner located by the A/C compressor, if it's squealing check the tensioner for sticking, the belt for wear and the pullys for bearing noise.
I don't know about that, like most all cars, you can tighten/loosen the belt by moving the alternator back and forth.
You can adjust the serpentine belt in about 5 mins. get a socket wrench preferably one with a swivel, and losen the top bolt of the alternator located on the back-top of the alternator, dont loosen too much, hard to tighten back up when TB is in the way. take a large prybar, find a solid point to put base of prybar up against, push top of prybar towards rear of vehicle till belt is at desired tension"may take a try or two" hold prybar in place till you can get bolt on alternator tightened. should be all set.

How do you replace the alternator on a 1993 Honda Accord?
Go buy the Chilton's Honda Repair Manual.
Unplug Battery, Slack belt tension, Remove mounts, Pull wires on back, Install new, Replace wiring and Belt, Attach Battery, test!
Either the battery is bad and won't accept a charge or the alternator is not putting a charge into the battery. Have the battery tested. You can hook up an inexpensive volt meter to the battery while the car is running. You should see from 13.5 to 14.5 volts if the alternator is working properly. If it is less than 13.5 volts then the alternator is not charging.

Where is alternator fuse located in 1995 Ford Taurus?
There isn't a fuse for the alternator. The alternator is belt driven, and there'll be two lines coming from the alternator - one goes from the alternator positive to battery positive, and the other goes to ground.
What is the difference between a dynamo and alternator?
A dynamo normally refers to a DC (Direct Current) generator. An alternator produces AC (Alternating Current) electricity. An alternator in a car actually generates 3 phase alternating current which is converted to direct current using a rectifier.
Generally, vehicle alternators are lighter, cheaper to produce, have better capacity over a wider range of speeds, take less maintenance and generally last longer than an equivalent generator. The one disadvantage is that they must have a battery in the circuit to excite the field coils.
There is no problem...the problem was the alternator. You have fixed the problem.
What will bad alternator do to a cars battery and lights?
A bad alternator will have the effect of draining the battery, resulting in dim lights, trouble starting the car and the like. It would be best to replace the alternator as soon as possible and possibly obtain a new battery. This may vary depending on how much the bad alternator has drained it. You can get your alternator and battery checked any time at Auto Zone.

How do you remove the airbags on a 1991 Lincoln Mark VII LSC?
The ~safety~ air bag on a 1991 should not be serviced by the vehicle owner. Replacement suspension air bags (springs) come with complete instructions (Arnott, StrutMasters, etc). The seller/manufacturer should gladly provide the buyer with a set even BEFORE purchasing the product. This is in their best interest to show you juyst how easy it is to install their product. If not, I'd move on to the next seller/manufacturer. Jack up your car, get to the air bag, turn the solenoid with vise grips, once the air is out turn the "fat" part at the top to unlock it. its kinda like your power steering cap on your car... it fits into place and turns to lock in. Now at the bottom of your a-arm remove the clip around the little stub that you see. kinda like a cotter pin... But like they said go to strutmasters.com and get some springs!!! 219.00 with shipping included and all instructions also. Hey also visit www.lincolnsonline.com
How do you know when you need an alternator?
A new battery or one that tested good is in the vehicle and the car is still losing power. the alternator is what charges the battery while the vehicle is operating.
What does it mean when alternator voltage reading starts at 14.5 then drops to 12.8?
I would suspect that the alternator is failing. Have it load tested at your local auto-parts store.
