3. Reconnect the battery terminals, ensuring a snug fit (positive first, then negative).

3. Test and Replace the Battery (if necessary)

Sub-steps:
1. Use a multimeter to measure the battery voltage; if it’s below 12.4V, proceed to replace it.
2. Remove the battery by unbolting it from the tray and lifting it out carefully.
3. Install the new battery by placing it in the tray and securing it with bolts.

4. Check and Replace Starter Motor (if necessary)

Sub-steps:
