Honda VT750CD ACE 3.5 Reading a Wiring Schematic When it comes to diagnosing and troubleshooting electrical problems, the most useful tool you can have at hand is a proper electrical schematic of your motorcycle. Learn to read it and become familiar with it and your time chasing electrical problems will be greatly reduced. - Page 17 Honda VT750CD ACE Most schematics will also have what's called "Switch Matrix" charts. These show the various switch positions and the switch leads that have continuity for each position. And example switch matrix is shown below. It shows that when you have the switch in the 'Left' position, the Orange and Gray wires are connected. When the switch is in the 'Normal' position, none of the wires are connected and when the switch is in the 'Right' position, the Gray and Blue wires are connected.
