I used the wrong crimping tool and was forever chasing electrical issues. Lesson learned! Over complicating an electrical system is usually the result of poor planning. The easiest way to wire a bike is to have all your connections in one place.

Then if you do have any problems you only have one place to look. I draw out the electrical components and lighting then work out how to best link them up.

Simplicity is such an important thing to me that I designed a component specifically to help people wire their bikes. The Purpose Built Moto Black Box will get those tidy handlebar switches and nice new lights working with only 11 wires.

This last mistake is a common one. This can work as a bandaid for years or it could burn your bike to the ground. Normally there will be an underlying issue with any fuse blow and it will most likely be the result of one of the 4 mistakes listed above. Here is my guide to standard motorcycle wire gauge and fuse applications. Your particular motorcycle may be different so take this as a suggestion rather than any kind of rulebook.

You should always work out the correct sizes using Ohms law and adding up the combined light wattage etc. If in doubt, ask an expert. Tom has published several other bike electrics articles that are available on the Purpose Built Moto website. He also publishes regular how-to videos on Youtube and sells his own electrical components in the Purpose Built Moto store.

Now Week Month. Testing for continuity allows you to find the short in an electrical circuit without dismantling the entire system. Turn the multimeter settings knob to "continuity.

This setting tests the amount of ohms at one end of a wire in relation to the ohms discharged from the other end. Unequal ohms measurements are evidence of a short in the wire. Place the negative multimeter probe, the black one, on one end of the wire you want to test for continuity.
