Our favorite analogy for the electrical system on vintage Honda motorcycles like the CB175, CB200, CB350, CB360, CB450, CB550, and CB750 families is to compare it to a sandwich. It is easy to get distracted by the multicolor wires that make up the middle toppings but you can not make a sandwich without the bread. In this video we cover the positive circuit, or the top piece of bread, to better help you understand what is happening in the middle.
Think of the positive circuit as two halves, one that runs from the battery to the key switch and another that runs from the key switch to nearly everything on the motorcycle. It is important to make this separation in your mind, as you will often hear the term " switched on 12v positive power " as the key switch plays a highly important role in both being the master disconnect as well as the point where the positive wires change colors from red to black. Be sure to watch until the end to understand not only the concept of the positive circuit but also how to practically test it and ensure it is working on your vintage Honda motorcycle.
