                                                                                                  An essential element for recharging the battery , the alternator is an essential component. This wearing part is one of your vehicle's consumables, which must be changed from time to time. In most failures, the regulator is the cause.

                                                                                                  What is the alternator regulator?

                                                                                                  Fixed to the alternator using two screws, the regulator consists of:

                                                                                                    • an electronic module which manages regularization.
                                                                                                    • two contact brushes inserted in brush holders, in support with the slip rings of the alternator rotor.
                                                                                                    • an external connector which allows connection with the vehicle's electrical harness.

                                                                                                  How does the alternator regulator work?

                                                                                                  To understand how the regulator works, you must first look at how the alternator works. It has different roles which ensure:

                                                                                                      • a production function : carried out by the stator, itself having 3 winding groups.
                                                                                                      • a rectification function : the diode bridge allows the alternating current to be redirected into direct current.
                                                                                                      • a regulation function : this is where the alternator regulator comes in. With the help of the rotor, it regulates the voltage. It is the regulator which allows, or not, the power supply to the rotor and the production of the required voltage.

                                                                                                  How do I know if my alternator regulator is no longer working?

                                                                                                  If the alternator regulator is not working properly, the battery light will be on on your dashboard. There is no direct way to check its proper functioning. To find out if the alternator regulator is faulty,it will be necessary to check all the other components of the alternator. You will then be able to deduce whether or not the problem comes from the regulator.

                                                                                                  AutoTruck42 provides you with quality brand alternator regulators: Bosh, Valéo, Iskra, Letrika, Ducellier, Paris-Rhône... We offer you the best brands at the best price !
