When you are listening to the radio in your Honda while you are driving, it may be surprising to find out that the battery is not powering it. In fact, the Honda alternator is the device that provides all the power while the engine is running. In addition, it does the very important job of recharging the battery at the same time. By using the motion of the rotating engine, through a belt connected to the crankshaft, the Honda alternator produces much more electricity than the battery can. The main purpose for the battery is simply to start the vehicle, and run accessories, such as the dome light, while the engine is off. There are many things that can cause the Honda alternator to stop functioning. Loose wiring harnesses are frequent culprits, as the alternator endures a large amount of vibration while it is running. If the belt that connects the Honda alternator to the crankshaft is loose and slipping, the ability to generate electricity may be greatly reduced. Corroded wiring is another common problem.

Diagnosing a Faulty Honda Alternator
The battery can easily run out of juice if not for the alternator that recycles the power used by the battery while driving. The alternator is there to make sure that battery power is enough and will last. The alternator also supplies power to a bunch of electric-powered components and accessories, so when it breaks or fails, there can be a breakdown of sorts. Some components will suddenly stop working. To help you figure out if your Honda alternator is failing, here are some diagnostic clues and troubleshooting tips:
Dim lights and other electrical failures
The alternator supplies power to electric-powered accessories of the vehicle, as well as the starter and ignition. When it starts to break or fail, the headlights and dashboard lights may become dim. If the lights are dim, you have to first identify the electrical fault. Find out if you have to change the bulbs or the lighting source, replace a blown fuse, fix a broken switch, or repair the electrical connection. If it turned out that the dim lights are due to a failing alternator, then be ready to replace the unit before it stops working completely.
A failing or bad alternator will naturally cause systems or electrical components to perform poorly. For instance, power windows or power seats may operate at a slower pace or rate than usual. There can also be problems with the power locks, A/C, and the radio. These components and devices may fail due to a variety of factors, but it would be best to check the alternator off your list when figuring out the underlying cause. The thing is, you wouldn‘t want the alternator to fail completely just when you least expect it. You'd want to replace it before this happens.
The vehicle may stall or may be hard to start due to a failing alternator. The alternator is supposed to supply power to the spark plugs. If there's not enough power, then the spark plugs won't be able to ignite the gasoline in the engine. Of course, the stalling and difficulty in starting the vehicle may also be caused by other problems. You have to trace the cause before replacing the alternator.
Flashing warning light
When the battery icon or the warning light on the dashboard flickers, you should take time to check the alternator. See if the light is triggered due to a weak or failing battery and not a faulty alternator. Also check the rest of the charging system to be sure.
The alternator recharges the battery to replenish it. However, there will come a time when the battery will die. To check if the problem lies with the alternator or the battery, what you can do is to re-charge the battery and then restart the vehicle. If the vehicle still has trouble starting even with a fully charged battery, the fault probably lies with the alternator. But if the vehicle will run yet the lights will become dim afterwards, then the trouble is likely with the charging system or because of a weak or dead battery.
Strange noises and odd smells
The alternator assembly has several parts inside it, some of which move or spin. When these components, such as the bearings or bushings, break or wear out, they may create a grinding or whining sound. Usually, the alternator is replaced as a complete unit or assembly. Aside from the strange sounds, a failing alternator can also be the source of a burning smell under the hood. The alternator works with belts. If the belt isn't turning smoothly, excessive friction can make it heat up, which leads to a burning rubber smell. The smell might be hinting on a slipping belt on the alternator pulley, which is causing the rather poor alternator output. You can adjust and tighten the belt in this case. Check if the belt is too loose or too tight or if it's cracked or worn out. If this doesn't work, then you may have to replace the alternator.
