Why wont my car wont turn on after I replaced my alternator belt?

The seized alternator will prevent the starter to turn the engine over and the engine will not start. If it didn’t start before replacing the belt, it won’t start after replacing it, simply because the battery is still dead.

Why is my car not starting with a new battery and alternator?

If the battery and the alternator are working correctly, then you might want to check for a blown fuse or a faulty ignition switch. In some situations, the ignition switch only provides power to the electrical components and avoids the engine starter, causing a “car won’t start after new battery installed” condition.

Can a serpentine belt cause your car not to start?

The short answer is yes, your car will start even if the serpentine belt is broken or missing. To get the car going, the battery sends power to your starter motor. However, you do need your serpentine belt if you want the car to run for longer than a few minutes.

What happens if serpentine belt is put on wrong?

In some instances it may be possible to install a serpentine belt the wrong way. If this happens, one or more pulleys will rotate in the WRONG direction, affecting the operation of the alternator, water pump, A/C compressor or power steering pump. This can cause major problems.

What could be the problem if your car won’t start?

If your vehicle won’t start, it’s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you’re dealing with a battery or an alternator problem.

Can a bad serpentine belt cause battery light to come on?

A failing alternator belt can cause the Battery Light to turn on, dimming or flickering lights in the car, and engine stalls.

What causes alternator belt to break?

The most serious failure is when the serpentine belt breaks completely. This is usually the result of a belt in poor condition, or a problem with one of the accessory components being driven by the belt. A failed bearing in a pulley being driven by the serpentine belt will also cause the belt to break.

Why does my car not start with a new battery and alternator?

With a new starter, battery, and alternator (assuming you have not drained the battery attempting to start it), the starter should attempt to crank over the engine. If the starter does not make any noise when the key it turned to crank over the engine, you have an issue with the fuses, or the circuit.

What should I do if my alternator keeps dying?

The alternator is essentially a generator and it keeps your battery charged while supplying additional electrical power for the other systems in the vehicle. If you have a new alternator and your battery keeps dying on you, then there’s definitely a problem that you’re going to need to look into.

How can I tell if my alternator is working or not?

If you’re not 100% sure, you can use a multimeter, or a voltmeter, to check the current coming from your battery. Attach the positive lead to the positive battery terminal, that’s the red one, and then the negative leave it to the black terminal. With the engine off you should be getting a reading of 12.5 volts on your multimeter.

Why is my alternator going over 14.8 volts?

If its going over 14.8 volts then your new alternator might be overcharging the battery. On turning key if starter clicks but does not turn then solenoid might have burned out. There can also be wiring issues or earthing issue or parasitic battery drain.
