is of adequate quality, but connections may come loose
or corrode, even on new motorcycles. When any circuit does not function correctly,
visually inspect wire runs to ensure that there are no shorts to the frame, and check the
related fuses, switches and connectors.
Switches with intermittent operation may just have oxidized contacts, which can often be
cleaned by saturating the switch with a contact lubricant such as WD40 and cycling the
switch. If lubricating the switch doesn’t restore operation, disassemble the switch, clean
contacts by scraping to shiny metal, lubricate, and reassemble.
The main fuse block is composed of metal connectors riveted onto a composite “bakelite”
insulator. Cracking of the insulator will allow the fuse contacts to lose tension. Cracked
insulators can be repaired by gluing with a high-strength “instant” gel adhesive. The
metal contacts of fuses must be clean and free of oxidation to reduce electrical resistance.
Some wire connections to assemblies such as turn lights are made by a screw connection
in a brass terminal block, which can loosen or oxidize enough to create an open circuit.
If there is no power to the center contact in a light socket, check the wire connections at
the back of the assembly, tightening the screws to ensure firm contact with the wires. For
spade-type connections, disconnecting and reconnecting the terminal will usually clean
the contact area to shiny metal. Corroded or oxidized connections should be pulled apart,
scraped clean, and lubricated with petroleum jelly.
