A damaged wire or component can cause a short circuit, leading to a blown fuse. It requires tracing the electrical system carefully to identify the source of the short.
Overload
If you've attached too many accessories or devices that draw power from the mower, it may overload the electrical system and blow the fuse. Reduce the load by removing or disconnecting nonessential accessories.
Faulty Fuse
Ensure that the fuse is the right size and type for the mower. A weak or damaged fuse may blow prematurely. Replace it with a fuse that matches the specifications in your mower's manual.
Faulty Component
A defective electrical component, such as the ignition coil, starter solenoid, or voltage regulator, can cause a short circuit and blow the fuse. Diagnose and replace the faulty component.
Loose Wiring Connections
Check for any loose or disconnected wires that may be causing intermittent contact and blowing the fuse. Tighten all wire connections.
