When your Nissan cannot start on a cold morning, it may not necessarily be the fault of the battery. The fault also may lie in the Nissan alternator. As the vehicle ages, the small pieces of metal that transfer the current from the moving portion of the Nissan alternator will begin to wear as well. When these devices, known as brushes, fail, the alternator may still continue to operate, because it is actually a set of three separate power generation circuits. The power that the Nissan alternator produces will be reduced to a certain extent, however. This means that the electronics in the vehicle will still receive power while the engine is running, but the battery may not receive enough power to be fully recharged. Extra demand is now placed on the remaining circuits, and this will hasten the complete demise of the Nissan alternator. When a replacement is needed, the high prices of the dealership do not have to be paid. Instead, take a look through our online catalog, and you will find a similar Nissan alternator for much less .Our version is just as good as the original unit, and it has a full warranty from the manufacturer to guarantee its quality. In order to install the Nissan alternator, the belt must first be removed. Then the bolts securing the Nissan alternator to the engine can be taken out, and the new part can be swapped with the old. When the belt is reattached, it is a good idea to check the repair manual to set the correct belt deflection. With our rapid shipping, the new Nissan alternator will arrive at your door soon.
How to Keep the Nissan Alternator in Good Running Condition
The alternator is driven by a belt and this spins quite a lot. While the alternator is built for the tough work, after some time, the bearings can go bad. The copper wire coils, carbon brushes, contact rings, voltage regulator, or magnets the produce the voltage may wear out as well. The unexpected failure of the alternator could leave you stranded in the road. So before it fails completely, watch out for the signs telling you that it's on its way out and know how you can test its condition and keep it up to snuff. Here are some maintenance tips for your Nissan alternator:
- Know when the car alternator is failing or on its way out.
Before your vehicle stalls, have it checked and rebuilt or replaced as needed. If the vehicle lights are dim or weak and if you notice that electrical accessories such as power windows and heated seats are sluggish, this could mean that the alternator is not working at its best since this is supposed to supply power to the vehicle's electrical system. If the car battery is weak or failing way ahead of the expected service life, it's another symptom of a faulty alternator. To find out if the battery is the one causing the problem or the alternator has something to do with it, try charging up the battery using jumper cables. Switch on the vehicle to see if it will start with a fully charged battery. If not, then the alternator has to be checked and replaced as needed. Strange noises and smells are another symptom of a weak alternator. If the belts that are linked to the alternator are no longer turning smoothly or freely, the friction can cause them to heat up and produce some brining rubber smell. The strange noises may come from parts that are worn out or don't turn well.
- Check the alternator if the battery-shaped warning light or charge icon comes on.
The warning light is telling you that something is probably wrong with the charging system, particularly the alternator output. So once it flickers, don't ignore it, especially when this lights up when using some of the electrical accessories of the vehicle. To pinpoint the faulty part, you have to check the charging system and test the alternator.
- Test the alternator to gauge its health or condition.
You can use a voltmeter (digital volt ohmmeter) to determine the condition of the alternator by measuring its electrical output. You have to switch off the engine before connecting the leads to the car battery. The red lead should go to the positive post, while the black lead should be connected to the negative post. Make sure that the voltmeter is set to DC volts or scale. The reading should be higher than 12.65 volts. After this, you have to remove the leads and then switch on the vehicle. Reconnect the leads and then check the voltage. It should read around 14 volts. If not, the alternator might be failing. Also check the voltage with the electrical devices on to see if the voltage will drop below 12 volts. See if the same voltage is registered at the alternator terminal to determine which is causing the problem, if it's the weak battery or the failing alternator.
- Keep the alternator from failing prematurely.
To keep the alternator working well, make sure that the protective engine undercover or shield isn't missing or damaged so that sand and water won't getting into the alternator. Replace a broken undershield as soon as possible so that the engine compartment will be clean and dry. Also check for coolant or oil leak. Identify where the leak is coming from and fix it before this contaminates the alternator.
