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.

  • Tips to Keep Your Nissan Frontier Alternator in Good Condition 04 March 2014

    Providing enough electric current to several electrically powered parts and equipment on your Nissan Frontier is made possible with an efficient alternator. Your car's alternator is crafted in such a way that it resists harmful elements and prevents early wear and tear. But overtime, this alternator will exhibit signs of aging and can cause serious power loss to your auto. If you want to extend your Nissan Frontier alternator's service life, then follow these quick and easy maintenance tips:

    • Schedule a regular checking and part diagnosis.
    • Performing a simple inspection on your Nissan Frontier's alternator can greatly aid in extending its service life. Checking the part at least once a month should be fine. When performing inspection, look for signs of corrosion in the wires leading to the alternator. A voltage-ohmmeter should indicate if the alternator is still working properly. In addition, check for any signs of cracks in the alternator belts and also make sure that they are secured tightly in place. A car's alternator can last even longer than 100,000 miles if taken care of properly. But if you reach this mileage point, expect to see some changes in the car's electrical parts. You see, you may experience dimming of your lights once the alternator reaches the brink of its service life.
    • Keep the alternator's wirings tightly secured and clean.
    • The cables attached to the alternator may move out of place overtime. So, checking them once in a while if they are secured tightly and firmly in place can extend the alternator's service life and prevent possible defects. Luckily, you only need simple tools like a wrench to tighten the nuts that hold the wiring to the alternator terminal. A wire brush works well in cleaning the terminals and cables.
    • Keep the alternator belts tight.
    • Aside from keeping the wirings in place, you should also make sure that the alternator belts are secured tightly to avoid power loss. Simply locate your alternator belts and find the two bolts that secure the alternator onto the engine. Loosen the bolts, but make sure that they are not undone completely. You see, a third bolt is present and it threads through an adjustable bracket. After loosening the third bolt, you can swivel the alternator away from the engine so that the belt is tightened.
