If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. You may also hear this sound if the bearings that spin the rotor shaft are going bad.
A foul odor of burning rubber or wires could indicate that parts of your alternator are starting to wear out. Similarly, if your alternator is being overworked or if it has frayed or damaged wires, you may smell a burning odor comparable to an electrical fire. An overworked alternator tries to push too much electricity through its wires, causing them to heat up unsafely. Damaged wires also create resistance to the flow of electricity, causing the wires to heat up and emit a foul odor.
However, the battery warning light indicates that there could be a problem within the wider electrical system of your car, including the alternator. Alternators are designed to work at a specific voltage, typically between If your alternator is failing, its voltage may drop below capacity, causing the battery warning light to appear on your dash. Similarly, the battery light will also appear if the alternator is exceeding its voltage limit, depending on how much stress it is under.

Meanwhile, an array of other systems from your headlights to your radio rely on electrical power provided by your battery. These two systems interact by means of the alternator, which transforms mechanical energy into electrical energy, thus keeping the battery charged. When an alternator stop working correctly, a wide range of problems may ensue.
This article takes a closer look at four commonly experienced symptoms of a failed alternator. If you jump start the car and it runs correctly, the problem likely stems from the battery itself. In some cases, the battery may have just become drained — for instance, if you forgot to turn your lights off. In such cases, jumping the battery and allowing your car to run for a few minutes fixes the problem. Because the car continues to run once started, you know that the alternator remains capable of performing its function.
Instead, the battery does not seem capable of holding a charge with the engine off. If your engine dies again within seconds or minutes of jumping the battery, the fault probably lies with your alternator. In fact, your alternator may have died completely.
In these cases, your alternator would fail and your battery would not charge. Alternators use the mechanical power of a belt and pulley to generate the electrical energy for the vehicle. The problem is that the alternator belt and pulleys are not too durable, which means they can easily break. Pulleys will typically last for a long time before they eventually get damaged from old age. Belts are flimsier and will eventually start to crack and even break after enough time. If either one of these things were to happen, there would be no mechanical energy being generated for the alternator to convert.
The root cause is probably not the alternator. What led you to change the alternator in the first place? I have a Santa Fe with automatic transmission, yesterday after a smooth brake I felt something happened in the car and then after a few km the car suddenly stopped fortunately close to the parking place and I just managed with several time use of jump starter get it to the parking. Or I can not turn off the front window heating when I start the car with jump starter.
It seems that alternator not working but I am almost sure there can be other root causes. Do you have any idea? Excessive jump starting can sometimes harm the electrical system of the vehicle.
