what would be causing my alternator to keep going out in my durango
A bad alternator can exit your Contrivance Durango without ability and unable to move. Alternators don't e'er go bad in the exact aforementioned way. We'll comprehend the symptoms of when an alternator goes bad, and how to diagnose a bad one (which is really pretty easy).
How Your Durango'due south Alternator Works
The alternator'southward job in your Durango is to provide electricity as it is running. The bombardment stores enough voltage to be able to start the engine without the assistance of an alternator.
It is turned by a serpentine belt. It's worth noting that a bad serpentine belt can cause the alternator to stop charging effectively. It's pretty easy to tell if one is bad. It'll look dry rotted. If information technology's been slipping a lot it'll have a glossy smooth to it. You lot'll accept probably heard it bleat when you beginning the engine. They typically don't fail quietly.
Symptoms of a Bad Alternator: Dodge Durango
Most of the time, when replacing an alternator, the alternator itself is relatively affordable. It's the labor that makes the job expensive. Hither are the about mutual symptoms of a bad alternator in a Dodge Durango:
Battery Light
The battery low-cal is designed to tell you that there is not enough voltage to properly accuse the battery, or that the bombardment itself is not holding the proper voltage.
In rare occasions the service engine soon light may light upward. Too, some vehicles accept an "alt" light that specifically tells you lot there is a trouble with the charging organisation, and not the bombardment itself.
Dead Battery
Outside of the battery warning light, a dead battery is the most common symptom of a bad alternator. As the alternator tin no longer supply your Durango with an adequate power supply, it will begin to feed off of the reserve in the battery.
Once this battery reserve hits a certain level, the vehicle will begin to run erratically and volition no longer starting time when the key is turned.
Frequently, the battery light volition come on, the alternator gets replaced, and and then a few days afterward the vehicle dies. That'southward why it's important to test the battery earlier you just replace it. Most any auto parts store will examination your bombardment for gratuitous to come across if it holds a charge. The procedure tin sometimes take an hour or so, but it'southward worth information technology to know before throwing money into a battery that you practice not need.
Stalling Engine
As described above, a bad alternator will drain your Durango's battery fast. When the battery gets so dead it will no longer exist able to power your Durango's ignition system. Equally the ignition system is no longer able to produce a full powered spark, the engine will begin to sputter and stall.
If yous notice yourself in a position where you doubtable that your voltage is dropping, but you need to safely go off the highway, turn off everything that you possibly can. Kill the radio, daytime running lights, air conditioning, heated seats, EVERYTHING. That will allow all of the limited voltage in the bombardment to become to the ignition organisation.
Bearing Noises
If your Durango's alternator starts to have bearings that fail, it'll begin to make some very obnoxious noises. If the serpentine belt has gone bad, it can brand some noises too, but it won't sound metallic similar the bearings going bad would.
Dim headlights
Dimming headlights are one of the near common signs of a bad alternator in the Dodge Durango. Dim headlights point that the alternator tin can't keep upward with the energy request for the lights. As your Durango begins to eat through the voltage stored in the bombardment, the headlights volition begin to fade.
Electric Accessory Issues
Many accessories in a vehicle require quite a fleck of voltage. Heated seats, the blower motor, power windows, and even the radio will piece of work erratically or not piece of work at all when the alternator is bad.
Dodge Durango Bad Alternator Diagnosis
Some alternators go bad right away, and some slowly lose their power to accuse under heavy loads. The ones that fail completely are like shooting fish in a barrel to diagnose. The bombardment drains and you are stuck with a vehicle that goes nowhere.
The claiming is diagnosing an alternator that is just non quite charging similar information technology needs to exist. You tin easily diagnose information technology with about any multimeter. Here'south what to do.
- Go a multimeter. They are cheap (you tin can become a decent 1 for $10), and you lot tin get them almost anywhere.
- Set it to read voltage. Specifically, you'll need to set it to 20V DC.
- With your Durango turned off, y'all'll connect the negative side of the meter to the negative battery post or wire. You'll and then touch on the positive side of the voltmeter to the positive battery wire. With the engine off, yous should get a reading somewhere between 12.0 volts and 12.six volts.
- Now that you have this baseline, information technology'south time to plough the engine on. Let'due south get ahead and go out the air conditioner off, as well as the headlights and any other accessories.
- With the engine but fired upward, yous should go over fourteen.ii volts. If you got fourteen.ii or more volts, the alternator is charging fine. If it's still showing in the 12's, it'southward time to replace the alternator. If it's producing a voltage level in the 13's, go alee and accept it into a parts store and have it tested. It's probably bad.
- Now, assuming that the alternator was producing over xiv volts, get alee and plow on the headlights, air conditioner, radio, and any other accessory y'all tin can call up of, and run the aforementioned test all again. If the voltage dropped back into the 12'south, it'southward a very stiff indication that the alternator is bad. It's still worth having it tested, but be prepared to replace it.
Some other exam y'all can exercise that'due south non nearly as scientific is to turn the headlights on and then beginning the engine. They should get brighter after the engine starts, since the voltage is increasing by almost 2 volts.
Now with the engine idling, rev information technology up a little flake. Did the headlights become brighter as you increment the RPM? This is a very strong indication that the alternator has in fact gone bad.
This test depends a lot on you to notice very subtle differences in lighting. It should not exist used in substitute for checking the voltage as described directly above.
Determination
Over the life of any vehicle, the alternator is going to go bad. Good luck diagnosing the alternator in your Durango. If there is annihilation that you would like to add together, please leave a comment below.
