The alternator works in conjunction with the battery to produce power for the electrical parts of the car. Alternators function by turning the mechanical action of the car's rotating drive shaft into electricity. They do this through the use of rapidly-spinning magnets. This magnetic field in turn produces an electrical current, which is used to power the car electrics. The alternator is also essential for re-charging the car battery, ready to provide the spark necessary to start the car next time.
The alternator bracket, usually made of steel or aluminium, functions as a casing or mounting for the alternator.
Usually alternators are fixed using alternator brackets that bolt to a particular part on the engine. One alternator bracket is usually fixed and doesn't move, while the other alternator bracket is able to move in order to control the drive belt.
If the alternator bracket has malfunctioned, it can do so without warning and can cause the drive belt to make a whining noise and eventually break if the problem is not addressed. As well as potential drive belt damage, a broken alternator bracket can cause the alternator to be sitting misaligned and can affect performance of this part. Constant vibration weakens the alternator bracket and can cause it to crack and break, but this damage can be slowed down if the alternator is bolted on tight enough to the Model> alternator bracket, which reduces excessive vibration to the alternator and alternator bracket.
