The alternator maintains the battery's charge level: when a malfunction occurs, the battery warning light on the dashboard illuminates, indicating a charging issue. You can attempt to repair the alternator as it is relatively straightforward to find replacement parts.

It is advisable to focus solely on replacing the brushes, as other components (like the diode plate or regulator) require more invasive disassembly and specific tools. Once the alternator is removed and placed on a workbench, remove the rear cover and inspect the wear on the brushes: if they are worn, note the codes on the label attached to the alternator and visit a specialist shop to purchase a new brush holder complete with brushes, and then replace it.
