  • Disconnect the negative terminal of the battery to ensure safety.
2. Inspect Battery and Connections
  • Sub-steps:
    • Remove the battery cover if applicable.
    • Clean any corrosion from battery terminals using a wire brush and a mixture of baking soda and water.
    • Tighten any loose connections securely.
3. Test and Replace Battery (if needed)
  • Sub-steps:
    • Use a load tester to check the battery's capacity; replace if it fails the test.
