How long does an alternator last?
That depends on a number of factors. On the average, you ought to be annoyed if your alternator goes bad in less than 5 years or 50K miles. The following will cause an alternator to fail quicker:high under-hood temperatureslots of high-draw electrical accessoriesweak batterybad jump-starting techniquedirt, water, sand, grease and foreign debris caked on, and in, the alternatorSometimes, what passes for a failed alternator is simply a bad diode pack. You might be able to swap a new diode pack in and get another 100K miles on the alternator.
How can you say diode is gone in generator bridge rectifier?
The most straightforward and unbiased way is to remove the diode from the circuit and check it with a diode tester. Alternatively, if the diode is shorted, the bridged will measure shorted. If it is open, running the generator and monitoring the output with an oscilloscope will reveal a missing phase. One example of an open diode problem in an automobile alternator application is that the alternator will put out enough current to keep the system fail light off, but not put out enough current to meet rated output load.
Can repairing a faulty alternator cause the air conditioning system to fail?
It could lead to it indirectly.
Why is your voltage warning light flickering -- and does it have anything to do with your 1986 Pontiac 6000 stalling once in a while only 65000 km on it?
Sounds like the Diode or the Voltage Regulator is going out on the alternator. I would recomend replacing soon. When one of those 2 componets go out, it really over heats the alternator. This causes the bearings on the back side of the alternator to fail, and sieze. This has cause some fires in GM cars and trucks.
Will covering an alternator with aluminum foil cause any damage to the alternator?
Yes it could, a alternator has air passages in its case to allow for cooling. If those holes are blocked the alt. could overheat and fail.
Can an alternator cause car to stall?
Not usually. The alternator can fail to charge enough, or even fail to charge at all, but usually the battery would carry the load for a day or two. - The answer is to charge your battery completely, over a 24 hour period then check the alternator with a good meter. First check battery voltage with engine OFF, this should be 12.1 -12.4 volts. Now start the engine and do the same test, voltage across battery should now be around 13-14.5. If still the same as static test then the alternator is faulty. You may not necessarily have to buy a new alternator, in many cases you can renew the 'diode pack' for much less cash. - -Go to a Starter and Alternator specialist shop for advice on this.
What would drain a car battery overnight on a 93 Ford Taurus?
If you're absolutely certain that the battery is ok (have it tested) and that nothing is being left on and that the key is turning off properly, it's time to have the alternator tested. Sometimes an internal diode can fail which will end up draining the battery. But don't just replace the alternator. Take the vehicle to your local auto parts retailer and have them test it for you IN CIRCUIT! Meaning that they'll test it with the vehicle running. They should be able to determine if the alternator diode has shorted.
What causes a diode to fail on a 240v solenoid valve?
Why would it? And is this the diode across the windings of the coil that supplies the back EMF (inductive kick) supression? There isn't a good reason for it to fail. A bit more information is needed here.
Why would your 1990 Mercury Cougar go through an alternator a year?
Hey Cari==Make sure there is good air flow around and through the alternator. Restrictions from heater hoses around alternators can cause them to overheat and fail. GoodluckJoe
Can Homework cause a student to fail?
If you don't do your homework -- yes, it will cause you to fail. Doing homework will not cause you to fail.
