How to Connect the Wiring for Motorcycle Ignition?
2 Answers
Motorcycle wiring for ignition is connected as follows: The black wire is from the magneto stator ignition coil and connects to the two-pin socket of the ignition unit. The blue-white and green-white wires are from the stator trigger coil and connect to the four-pin socket of the ignition unit. The red and yellow wires are from the lighting coil and connect to the rectifier. The ignition unit has a total of two wires that need to be connected, while the rest can simply be plugged in. A motorcycle is a two- or three-wheeled vehicle driven by a gasoline engine, steered by handlebars for front-wheel turning. It is characterized by being lightweight, flexible, and fast, widely used for patrol, passenger and cargo transportation, etc. Motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.
Last time I was working on an old motorcycle's ignition system, I discovered a standard procedure: always disconnect the battery negative terminal first! Never skip this step—seeing sparks fly from a short circuit is terrifying. Locate the thin red wire behind the ignition switch, which is the power line, and use a multimeter to confirm the circuit is dead before proceeding. The ignition switch wire should connect to the input of the ignition unit, while the thick blue wire from the output must link to the ignition coil—don’t forget to cover it with heat shrink tubing to prevent shorts. Connect the battery positive directly to the large terminal of the starter relay, and make sure the frame grounding point is sanded clean and the bolt is tightened. Before test-running, I always connect a 12V bulb in place of the fuse—if it lights up, the circuit is complete. Rewiring like this can’t be rushed; my Jialing 70 took three weekends to get right.
