Ensure safety by disconnecting the negative battery terminal.

2. Battery Inspection and Replacement

Step 1: Clean battery terminals.
- Use terminal cleaner to remove any corrosion.
Step 2: Test battery condition.
- If voltage is below 12.4 volts, charge the battery or replace it if necessary.

3. Check and Replace Fuses

Step 1: Locate the fuse box.
- Refer to the owner's manual for the exact location.
Step 2: Inspect fuses related to the starting and ignition system.
- Replace any blown fuses with the correct amperage.

4. Ignition Switch Testing
