⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems
•Allow the engine to cool before inspecting components

Symptoms

•Dashboard lights flickering intermittently
•Possible dimming or brightening of lights
•Warning lights may illuminate briefly
•Electrical components (e.g., radio, windows) may malfunction
•Battery warning light may appear
•Engine may exhibit stalling or rough running

Diagnostic Steps

1
Check the battery voltage using a multimeter to ensure it is within the normal range (12.4-12.7 volts)
2
Inspect battery terminals and ground connections for corrosion or looseness
3
Scan for error codes using an OBD-II scanner to identify any related fault codes
4
Examine the alternator output to verify it is charging the battery correctly (should be around 13.8-14.5 volts with the engine running)
5
Inspect the wiring harness and connectors for signs of wear, damage, or loose connections
6
Check the fuses related to the dashboard and electrical systems for any blown fuses
