Power supply harness, crimp terminal, socket, fuse, trailer hose hanger

This category brings together parts used when modifying electrical wiring in trucks. We sell power extraction harnesses that supply power from inside the truck's cab to the onboard electrical equipment and bodywork, crimp terminals and terminal covers used in modifying electrical circuits, high-current fuses, and sockets and plugs for connecting trailer wiring.

What is a fuse? Explaining its role and usage

A fuse is a component that protects electrical circuits. When an excessive current flows through the fuse, the internal circuit breaks, cutting off the electrical circuit.

Under normal use, a current large enough to blow a fuse does not flow. However, if a short circuit occurs due to unexpected mechanical load, a torn or broken coating due to aging, or water damage, a large current will flow and the fuse will blow. Without the fuse, not only the electronic equipment but also the wiring would burn out, requiring extensive repairs.

Yamada Body Works sells "MEGA Fuses 100A-250A" and "MEGA Fuse Holders." These products are fuses designed for relatively large currents, such as those that flow through motors in hydraulic devices like power gates and wings. If the fuse blows immediately after being replaced, investigate the cause of the large current.

Crimp terminals (bullet terminals) are essential when connecting electrical wiring.

Crimp terminals are essential when connecting electrical circuits. They are used to connect the wiring of various electrical components, such as truck lights and audio equipment.

There are two types of crimp terminals, male and female, and connections can be made by simply attaching each terminal to two wires using a tool called electrician's pliers. Crimp terminals are electrically conductive, and will short out if they come into contact with the body ground, so be sure to insulate them using a "crimp terminal cover" or "Denka satin tape." Wires used outside the car will get wet in the rain, so they need to be properly waterproofed with tape.
