  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Battery Inspection
  1. Disconnect Battery: Remove the negative cable from the battery terminal to ensure safety.
  2. Check Battery Voltage: Use a multimeter to measure the battery voltage. If below 12.4 volts, consider charging or replacing the battery.
  3. Clean Terminals: Clean the battery terminals and connections using a wire brush.
3. Alternator Testing
  1. Reconnect Battery: Reconnect the battery.
  2. Start Engine: Start the engine and allow it to idle.
  3. Measure Alternator Output: Use a multimeter to measure the voltage at the battery terminals. The reading should be between 13.8-14.2 volts. If lower, replace the alternator.
4. Ground Connections
  1. Locate Ground Points: Identify all ground points related to the headlights and battery.
  2. Inspect and Clean: Check for corrosion or looseness. Clean any corroded connections with a wire brush and re-tighten.
5. Wiring Inspection
