Troubleshooting After Replacement
Starter problemsmay appear after replacing a mower battery. The mower might not start or make clicking sounds. This often happens because the battery is not fully charged or the connections are loose. Check the battery terminals for dirt or corrosion. Tighten the cables to ensure good contact. Testing the battery voltage can help. A low voltage means the battery needs charging or replacement.
Electrical issuescould cause the mower to stop working properly. Faulty wiring or blown fuses might be the cause. Look for damaged wires or disconnected plugs. Use a multimeter to check the fuses and wires for continuity. Replacing a fuse or fixing a wire can solve the problem. Also, verify the ignition switch is working correctly.
