In the 1984 Kawasaki Ninja, the battery is typically located under the seat. To access it, you'll need to remove the seat, which is secured by a few bolts or a locking mechanism. Once the seat is removed, you should see the battery compartment, allowing for easy maintenance or replacement.
To remove the passenger seat on a Kawasaki Ninja, first locate the seat release mechanism, usually found near the rear of the seat or under the seat itself. Use a key or a tool to unlock it, then lift the seat gently to detach it from the bike. Ensure that any clips or fasteners are completely disengaged before fully removing the seat. Always consult your specific model's owner manual for detailed instructions, as the process may vary slightly.
