INFINITI M35 brake light and battery light issue persists after alternator replacement on INFINITI M35

Some INFINITI M35 owners report experiencing persistent brake light and battery light illumination even after replacing the alternator. This issue may arise from improper installation during the alternator replacement, which can lead to the warning lights remaining on. Additionally, some owners encounter computer or electrical issues that require advanced diagnostics, as newer vehicles often have complex systems that can trigger faults. The battery warning light may also indicate problems with the battery itself, particularly if it is old or corroded, or issues with battery cables. Furthermore, electrical grounding problems can cause the brake and battery lights to flicker or stay illuminated, especially when driving over bumps. To resolve these issues, owners are advised to ensure proper alternator installation, conduct advanced diagnostics, check the battery and charging system for faults, and examine grounding connections to rule out any grounding issues.
