The alternator is relatively a simple component, as it contains only a few parts, but still plays a key role in the operation of any fuel-efficient vehicle. The alternator converts the mechanical power of the engine crankshaft into electricity through induction. The wires inside the alternator cross the magnetic field; therefore causing electrical shock. That camera is used to power your car’s accessories, which can be anything from headlights to electro-hydraulic snow plows.
The alternator also keeps the battery fully charged, providing the power it needs to start the car. Electric vehicles do not require alternators as they are powered by a combination of electric motors and batteries that provide maximum performance for normal vehicle operation.
Because the alternator is connected to other vehicle systems, any automotive mechanical problems can affect its function and contribute to diagnosing vehicle problems. Paying attention to the 5 signs of problems in this list can make it easier to identify an auto problem caused by an alternator, which helps to sort out the problem of a changed alternator now car won’t start.

Reasons Why Changed Alternator Now Car Won’t Start?
Here are some problems related to Alternator
1. Warning Light
Within a set of tools for many vehicles built over the past decade, a warning light is provided to sign the alternator problem. In most cases the battery is light, or some other indicator is “ALT” or “GEN,” meaning alternator or generator, respectively. In some older cars, the alternator is referred to as a generator,
What can you do about it?
- Check the electrical connection in the alternator to make sure it is safe and secure.
2. Dim Lights
Your car may be experiencing a variety of symptoms ranging from dull or dim lighting to dash lights, to speedometers and tachometers that simply stop working for no apparent reason.
What can you do about it?
- Disconnect the negative terminal from the battery using a screwdriver to release the nut.
- Loosen the generator tensioner with a screw and remove the accessory belt.
- Remove the alternator bolt bolts using a socket and ratchet. Pull the alternator out of the Sorento.
- Install a new alternator on the engine and tighten the mounting bolts with a socket and ratchet.
- Place the accessory belt on the alternator. Tighten the belt by tightening the tensioner bolt with a screw.
- Reconnect the battery terminal and tighten the nut with a screwdriver.
3. Flickering Lights
On the previous page, you learned that faint light on the outside and inside is a common symptom of an alternator problem. If your lights are dim, then there may be two symptoms that are often related, but not always.
If your lights are on, then dim, and then on again (either in normal rhythms or in random appearances) then you have a problem with your electrical system, and the alternator is likely to be faulty.
The assumption is that the lights are just dimmed – the alternator does not produce enough juice to keep the lights running at full power, and instead of dimming all the lights by turning, your car tries, and fails, to maintain proper lighting output.
What can you do about it?
- If you see in the dipstick a low oil level, you can try adding more oil to see if the problem is fixed. Add the same engine oil. Try not to mix oil viscosity, as it is not recommended. But in this critical situation, you can mix the engine oil until you get to the nearest repair shop, clean the engine completely, add new oil and change the oil filter.
- If this does not fix the problem, try not driving with a light oil lamp. This can cause some damage to the engine which may be costly to repair. Instead, try to drag the car to the repair shop for a closer look.
4. Dead Battery
A car that does not start is a clear indication that there is a problem with the initial system. When the key is turned on, you will hear a noise but nothing would happen. After a while, that noise stops. A quick problem is usually a dead battery, but you need to ask “Why is it dead?”
When the alternator starts to fail – or fails – the car battery starts to take off instead of acting as a system capacitor by experiencing constant power outages in the alternator.
However, even the best car battery will eventually drop out, so leaving you trapped in the roadway or worse, off the road. Car batteries are not designed for long-term use.
They are designed to provide your car with enough power to start by launching the launcher engine with great power and making all the tasks go around. In other words, a bad alternator can get your attention by killing your car battery, even if the battery was not a problem at first.
What can you do about it?
- Always keep the jumper cable on your car pole in emergencies. If you do not know how to jump the car with a jumper cable, see your owner’s manual for help or call a mechanic. You will need a good battery or a portable jump starter to charge your weak battery.
- The mechanic will use a voltmeter to measure the energy level.
- If the battery does not pass the test, you will need to replace a dead or weak battery.
5. Bad Starter Motor
A starter motor is a device that rotates an internal combustion engine to initiate engine performance under its power.
It has a small cylinder-mounted component – a starter solenoid – that transmits electrical energy from the battery to the starter motor to propel the car’s engine.
If the launcher engine or solenoid launcher is broken, your car will not start. So how can you tell if you have a faulty start car or a solenoid?
Here are some of the signs:
Your car’s engine will not start
Your engine may be moving too slowly
When you start a car engine, you may notice a rustling or turbulent sound
What can you do about it?
- If you experience any of these symptoms, you may need to have your starting or beginning solenoid changed by a repair
Conclusion
Changed alternator now car won’t Start: There are various reasons as you can see.
However, whether the issue is caused by a defective battery, a malfunctioning alternator, a blown fuse, or a bad fuel pump, the majority of the symptoms are the same. Some of these may even be a signal of a more serious underlying problem that only professionals can detect.
That is why, when it comes to troubleshooting beginning problems, you should always seek expert help.
