Because the alternator puts a load on the engine of several horsepower, the belt must be very tight. However, if it is too tight, the bearings of the alternator shaft will wear out quickly. To tension the belt properly, adjust until there is about 1/2 inch of play in the center of the longest span. If this does not stop the squealing, the belt may have been glazed from being too loose, and needs to be replaced.
Remove the upper through bolt of the alternator, remove the bottom bolt of the alternator by unscrewing the nut. Slide the belt off pulley. Install the new alternator. Replace and tighten the bolts (You will need to use a torque wrench to tighten to the proper foot-pounds of torque. You can find the torque specs for you bolts by going to a Honda forum). Adjust the tension bolt until there is enough tension on the belt (if not enough tension you will hear the belt squeak when you stat your car).
The alternator may be out of alignment. Put soap on the inside of the belt and it will turn the grooved part white enough to be able to see if the belt is not running straight. If the belt is all aligned on the lower pulleys and then jogs off to the side the higher it gets, it's the alternator in the back of the engine. There is an adjustment on the bracket that connects to the intake manifold, but most likely you'll have to take the alternator out and adjust the swivel part too. There is a spacer in the swivel part on the bottom of the alternator that you can hammer one way or the other. I had to put in a couple of washers to make up for the space on the other side. I hope this helps.
It Could Be Your Serpentine Belt too tight or not tight enough.
It's probably the belt slipping. Check for belt tension. When an engine first starts the alternator works harder to recharge the battery. During that time, the alternator is harder to turn and if the belt isn't tight enough there can be some slipping between the belt and the pulley.
If the bearings in the alternator get bad enough it can lock up.
depends on what way you are testing it but you either have a bad connection between the alternator and the battery or your battery is bad and cant hold the charge what voltage are you getting
Not enough belt tension.
Alternator is not making enough power.
Not a good sign, This could mean that your charging system (alternator) isn't doing its job. If you have problems starting the car due to not enough battery power, then check your battery to see if it is holding the charge. If after a while that you had to boost or jumpstart your battery your car gradually dies then check your alternator to see if it is putting out charge to the battery.
I have the dreaded belt squeals, this happened after a valve job and the dealer didnt tighten the belts enough. Like the A/C compressor the alternator has an adjusting stud, a pivot bolt and a tightening bolt, this is what I can not find. I found all 3 components on the a/c compressor but am still looking for the altSomewhere it was said that it's the same as in the 91 Honda Accord.IF true..Both the alternator and the AC compressor run off the SAME belt.And ther is NO adjusting stud, etc. on the alternator.Soo..Please tell me How to get to the AC adjust components.(with only one belt, it makes no sense for BOTH to have adjustors.)start off by taking out the power steering pump..one of the bolts you have to look through the pully to see it...it has 2 10mm bolts that hold the tensioner.the top blot on it is a 14mm and the bottom blot is a 12mm.....pull off the belt......next step is the alternator remove the 10mm tensioner blots...remove the belt....take out the top and bottom bolt and remove the alternator....putting it back in is the same why you took it out...hope this helps you out..Additional info: The AC compressor does NOT have a tensioner. It does operate from the same belt as the alternator and the adjuster on the alternator is the one used. The power steering pump has it's own belt and adjuster.
The alternator must be removed and replaced from the bottom, as with raising the vehicle high enough to work from underneath "safely".
No alternator should EVER charge at 27 volts. That's enough voltage to burn up the computer.
It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
The alternator slides with the alternator bracket. Loosen the bolt that goes through the bracket into the alternator. You may need to loosen the bolt on the bottom as well. Don't remove either. Then slide the alternator towards the opposing pulley to loosen the belt enough to disengage.
I've got the V6, just remove the radiator fan directly in front of the alternator. The fan has 2 screw bolts(10mm) on top, 1 on bottom(which I could just manage to access from the top with a deep socket), unplug the wires and you can lift it out of the way. This gives you enough clearance to remove the alternator (be careful not to ding your radiator though). Also, I didn't relized that the tensioner pulley was a spring-loaded type...I've never seen one till now. Just put a wrench on the middle of the pulley and you can adjust it to move the alternater back in place. Another tip, since you're replacing the alternator, might as well replace the belt too. Good luck. 2hours - not hard, just hard to get to till you figure out what items you need to move out of the way.
What is your question? You have not asked a question or provided enough information for an answer to be given. The 1989 Honda Accord contains no Freon. It contains R134a refrigerant.
There are two reasons this could occur. The first is the alternator may not be receiving enough power from the battery and the other option is there may be faulty wiring on the motor of the alternator.
The working principle of an alternator is like that of a small turbine. The alternator spins and a series of copper wires and graphite brushes inside the alternator produce electricity. That electricity is then transferred to the battery to keep it charged enough to run all of the electric parts on the vehicle.
I just had my alternator replaced (at a shop). They told me the mechanic had to "rip the entire front end off" to get to it.
get a wrench that fits the tensioner and pull it back until the belt has enough slack to go on the alternator
It may be the result of a malfunctioning alternator, or simply a loose alternator belt. When the car is idling, the rpm's of the engine are decreased. This means that the battery is putting out energy, but the engine is not moving the alternator fast enough to refill the charge. When the car is moving, the alternator is getting enough power to keep the lights from dimming.
Until the battery gets low enough that it will no longer provide enough spark to excite for combustion.
The Alternator is not putting out enough voltage. If you recently replaced the alternator with a "new" remanufactured alternator that one could be bad to your truck somewhere to get it tested.
To replace the alternator you must tip the motor. by removing the motor mounts in front on the motor.just the two top ones and than roll the motor forward. that will give you enough room to remove the alternator
the belt probly is not tight enough
