What is the method for starting a motorcycle with 4 wires?

Motorcycle with 4 wires starting method is: 1. Connect the red wire to the positive terminal of the battery; 2. Use a multimeter to measure which wire is conducting with the red wire after turning the key, and find the power supply wire for the whole vehicle; 3. Connect the red wire to the power supply wire, and the power can be turned on after turning the key. The maintenance methods for motorcycles are: 1. During the break-in period, control the motorcycle idle speed at 100 rpm; 2. Match the motorcycle gear with the speed; 3. When you need to brake due to an obstacle ahead, release the throttle, step on the rear brake with your right foot, and gently apply the front brake with your right hand; 4. Regularly check the spark plug; 5. When installing a new spark plug, hand-tighten it until it cannot be turned anymore, then use a spark plug socket to tighten it a quarter to half a turn; 6. Regularly lubricate the chain.
I remember when my motorcycle key broke before, I had to start it manually. Those four wires are usually the red one connected to the battery positive, the black one to ground, the yellow one is the ignition signal, and the blue one is the starter motor. I first disconnected the battery negative to prevent a short circuit and operated with gloves on. I briefly shorted the red and blue wires to simulate the starter switch while grounding the yellow wire to trigger the ignition coil to produce a spark. Once the engine started, I immediately disconnected the connections. This method works in an emergency, but it's easy to get an electric shock or blow a fuse. My lesson learned is to quickly go to the repair shop to replace the faulty parts and regularly check the ignition system to prevent such failures, so as not to scramble for a last-minute fix.
