What kind of bike do you have? No matter what your answer is, if it’s one that you intend to live with or work on for any amount of time, one of the single best things you can do for both it and yourself is get your hands on a shop manual. If you’re the type of person who’s both curious and also willing to indulge your curiosity, you could end up learning a whole lot more about your particular machine than you know right now.
That’s just one of the points that BJ of Brick House Builds makes in this helpful video about diagnosing electrical issues. While he uses his Honda CB750 to demonstrate, the point isn’t learning the intricacies of wiring on a CB750. Instead, it’s learning how to trace out potential issues on a wiring diagram, then chase them down and do a little investigation on your specific bike, so hopefully you can both diagnose and solve your specific problem.
