Attach the positive cable to the positive terminal. Ensure the connection is secure. Next, attach the negative cable to the negative terminal. Make sure it is also secure.
Tighten Connections
Use a wrench to tighten the connections. Start with the positive terminal. Turn the wrench clockwise to secure. Repeat this step for the negative terminal. Check both connections for tightness. Loose connections can cause issues. A secure connection ensures proper battery function.
