Sooner or later you will need to find a failing component, a broken wire, or a short. Or, you will attempt to add a new device to your motorcycle and have to do some wiring. Stay away from them. If the failing fuse is not visibly burnt it is often just fractured as a result of age.
Crimp connectors are a NO-NO on motorcycles.
Vibration and weathering will eventually make them fail. Solder all wire joints you make and use a piece of shrink-wrap tubing to finish the job. Solid wires are a NO-NO on motorcycles. Vibration tends to fracture them. Always use stranded wire.
