How To Install An Inline Fuse

This modern was the next logical step on my beloved CB later on replacing the stock handlebars with a pair of Biltwell Trackers, so hither's a little write up on how to install the venerable inline fuse holder on a vintage motorbike.

An inline fuse holder works wonders when rerouting wires on a vintage wheel. Whether information technology is for aesthetic or functional purposes an inline fuse is a handy modification to make clean things up. On vintage bikes the electrical is often corroded and weak...converting to inline can set up this by rerouting the wiring from the corroded original connectedness to a shiny brand new one. Aesthetically it minimizes the bird's nest of wiring upwardly front past enabling yous to hide a lot of messy wiring/connections under the gas tank or in the headlight saucepan.

My motivation was aesthetic as well every bit functional: the 1979 CB750k has a fuse cake that sits correct in the center of the handlebars and acts as the clamp to the risers. I wanted to clean upwardly the cockpit and ditching that fuse cake was a necessity. Besides, the prongs that held the headlight fuse were and so corroded and rusted that they wouldn't secure the fuse. My options were to buy a new fuse box or to reroute the wires. I opted for the latter.

Here's how to go it done, stride-by-step:

Yous can see the bulky fuse box in a higher place. And if you lot look close y'all can see the fuse slot furthest left has a corroded connexion. Information technology would just work with foil wrapped around the fuse to maintain contact. And while Reynolds wrap is fine for roofing windows and constructing conflicting-proof head clothing, it has no identify on my off-white steed.

Unscrew the fuse box and pull information technology out. Cut each wire, notation the color of each and it'due south function (headlight, turn signals, brake light, etc. A piece of masking tape and a magic mark can exist helpful here). You'll cut the hot wire besides, in this case it's the thicker blackness 1 in the centre of the box. Keep runway of your hot wire, you'll need to wire it in at the stop.

Pictured in a higher place is the inline fuse holder. Strip the wire on each stop about 1/iv" then do the same on the fuse wires. Plainly wire strippers make that easier, but if your tool pick is defective you lot can always merely make a shallow cut in the wire insulation with an exacto knife and and then pull off the tip with pliers. Just don't cutting too deep and sever any wire threads.

For each private power supply you will require an individual inline fuse holder. Connect the headlight wire to one, the brake light wire to some other and and then on then forth.

You can buy all-weather barrel connectors inexpensively from any automotive store. Insert the wire ends into the butt connectors and have wire crimpers (or pliers) and crimp the wires deeply. Don't forget to take previously slid your heat shrink around the wire and so that once the butt connectors are attached you tin slide the rut compress over the connectedness. Any heat source will work to activate the estrus compress, I used a standard BIC lighter. No longer than a second or two of exposure to the heat source is required. With the crimped butt connectors and heat shrink in place your inline fuse holders should be attached similar the prototype in a higher place.

At this point the inline fuse holders should be deeply connected to the wiring on one side and loose on the other. The loose ends will need to be connected to the hot wire. I don't employ turn signals or a neutral low-cal on my wheel, so I was only wiring up two connections (headlight and restriction calorie-free). You lot tin can encounter in the above picture show the loose ends of the ii inline holders and the loose cease of the hot wire (thick blackness wire). Once more, using an all conditions barrel connector, heat compress, and then some electrical record for good measure I continued the wires.

In the end you should have some iteration of this: divide wires going into each inline fuse holder, and 1 hot wire connected to the other end of each inline fuse holder. I then tucked this trivial loop of wires into my headlight saucepan and was left with no need for the original fuse block. A functional headlight with no unsightly wires sticking up around the handlebars: Success.
