You know, the alternator is one of the most important parts of your vehicle. The alternator is responsible for charging the battery and the battery is responsible for providing the power to all the electrical components. If your vehicle is not getting enough power from the battery, then it is very difficult to run your vehicle.
It is quite possible that your new alternator and voltage regulator still not charging might be faulty. If this is the case, then it will be a great idea to replace them.
Reasons why a new alternator and voltage regulator not charging:
Overheating of the alternator:
If your alternator is overheating then it will reduce the lifespan of the alternator. As a result, it will become useless. Mostly it overheats due to loose wiring, poor battery or poor alignment. It is detected by a burning smell coming from it.
Overheating of the voltage regulator:
If your voltage regulator is overheating then it will reduce the lifespan of the voltage regulator. As a result, it will become useless. It is due to if the voltage is faulty and the link is bad, this may cause the regulator rectifier to run hotter than usual.
Overheating of the battery:
If the battery is overheating then it will not work properly. Mostly over charging can also overheat the battery.
Low voltage of the battery:
If the voltage of the battery is low, then it will not charge the battery. As a result the charging of the battery is poor and will not provide the required power to the electrical components.
Here are some reasons why a new alternator and voltage regulator still not charging:
I’m going to assume that you’ve already checked all of the obvious things, such as making sure the battery terminals are connected and the cables are properly connected. If you haven’t, you can find out how to check those things easily.
If the charger is plugged into an outlet and the battery is fully charged, then you know it’s charging. That’s the easy part.
But what if it’s charging, but nothing is happening? That’s the real question.
There are a lot of reasons that a charger may not be charging. It could be a bad battery, but the most common reason is a bad alternator.
It’s possible that the voltage regulator on the alternator is bad, too. If that’s the case, it won’t be charging at all.
In that case, there’s nothing wrong with the battery. It’s the alternator that’s the issue.
You can test this by disconnecting the negative terminal on the battery. Then connect the negative terminal to the positive terminal of the alternator. If that works, you know it’s a bad alternator.
If the alternator still doesn’t work, then you need to get a new alternator. There are several different brands of alternators available.
My recommendation is to use the same brand as the one that came with your car. They’re generally more reliable than aftermarket alternatives.
If you have a manual transmission, you might want to consider a universal alternator. It’s designed for manual transmissions.
If you have an automatic transmission, you might want to consider a dual-voltage alternator. It’s designed for both manual and automatic transmissions.
