Nissan Frontier Alternator
Reasons behind Nissan Frontier Alternator Problems
A tough pickup truck like your Nissan Frontier needs a tough alternator to provide enough electric current to several parts of your auto. The parts include the lighting, heating and cooling units, and other electrically powered equipment. However, despite its durability, your vehicle's alternator is still susceptible to wear and tear. If you suspect sudden electrical issues caused by a faulty alternator, you'd better perform some troubleshooting. Listed below are some of the common problems encountered with a faulty Nissan Frontier alternator and the reasons behind them.
Loss of power
If you suddenly experience difficulty in starting your Nissan Frontier, or if you find abnormalities in several electrical parts like the radio and the clock, then you might have an alternator problem. The easiest way to test for a defective one is to disconnect the battery while the auto is running and performing a voltage test. An alternator in good condition should allow the car to run even if the battery is disconnected. If this is not the case, then you definitely have an alternator problem. You can detect if the alternator is not providing enough voltage with a voltage-ohmmeter. This device is widely available in the market, so finding one shouldn't be much of a drag. An alternator in good condition should read around 13.8 to 14.2 volts on the device.
Poor electrical output
Your car's poor electrical output may be attributed to faulty alternator belts. To troubleshoot, simply check the belts if they are already worn out or if they are not secured tightly in place. An alternator with signs of wearing prevents the car battery from fully charging. Also, a loose alternator belt prevents the part from running at standard speed, so it will not provide the right amount of voltage.
Too much alternator noise
Aside from a loose drive belt, too much alternator noise may be caused by a defective diode or worn bearings. This excessive noise may even be coupled with a burning smell from frozen bearings. You see, these damaged bearing parts can cause an irritating, cracking noise. This can also indicate that something loose is inside the alternator body. So, before you have poor power production, check out the noise that's coming from your alternator because it might be a symptom of an even bigger problem.
