However, before jumping into conclusions, check your mower's maintenance history. If you've recently mowed your lawn, the battery may just need a full charge or replacement, especially if it's older than three years.

Diagnosing a Dead Battery

Check your battery's charge level. A fully charged battery should read 12.6 volts or higher. If it's significantly lower, it may need replacing. Ensure the battery terminals are clean and free of corrosion.

If the battery checks out, proceed to the next electrical component: the spark plug. Remove it and examine its condition. If it's worn out or fouled, replace it with a new one to regain reliable sparking and engine operation.

Checking the Wiring
