Plug the learning wires together, then plug in the power key, turn on the power, and see if the motor rotates automatically. If it rotates forward, just unplug the learning wire directly. If it rotates in reverse, unplug the learning wire and re-plug it to rotate forward, and then unplug the learning wire to complete the learning (after this step is completed, the motor automatically rotates to prove that the controller is good, and if it does not rotate, it proves that there is a problem with the controller)\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S3e6a9d803fcd48f6ac30f7bac9c905a2W.jpg\"\u003eSTEP 4. 4 Connect the Hall wire\u003c\/p\u003e\n\u003cp\u003ePlug in the Hall wire, which has 5 wires with one head. Note: The Hall wire has positive and negative poles. The positive pole of the Hall wire of our controller is red, and the negative pole is black. As long as the positive and negative poles are correct, it doesn't matter if the other 3 wires have different colors. Our controller is a brushless controller, which can be used with or without Hall wires. However, if the Hall wire of the electric vehicle motor is broken, the following situations will occur: 1. The vehicle will shake and be weak when starting, but it will be fine when riding; 2. The anti-theft alarm can be used, but the motor lock function cannot be used; 3. The high gear of the three-speed cannot be used, but the low gear can be used\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSTEP 5. 5 Connect the throttle wire\u003c\/p\u003e\n\u003cp\u003eFind the throttle wire for control: red, green, and black. Red is the positive pole of the throttle, black is the negative pole of the throttle, and green is the signal wire of the throttle. Then find the throttle wire on the electric vehicle; note that the throttle wire of the electric vehicle must come out of the throttle. If necessary, you can disassemble the throttle to identify which one is the throttle connector in the electric vehicle, connect the throttle connector, turn the throttle, and see if the motor rotates. If there is no response when turning the throttle at this time:\u003c\/p\u003e\n\u003cp\u003e1. The positive and negative poles of the throttle are not connected correctly;\u003c\/p\u003e\n\u003cp\u003e2. The throttle is broken; just change the throttle. (Friends with a multimeter can use the multimeter to test the throttle signal wire to see if there is a voltage output. Set the multimeter to the voltage output state, connect the red needle to the green signal wire of the throttle, and connect the black needle to the black ground wire of the throttle to see if there is a 0-5V voltage. If there is no voltage, it proves that the throttle is broken. Be sure to connect the controller and the throttle and turn on the power to test; otherwise, it will not work.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSTEP 6. 6 Connect high and low battery brake wires\u003c\/p\u003e\n\u003cp\u003e1. The controller has both a single yellow high battery brake wire and a white and black low battery brake wire. High battery brakes and low battery brakes are distinguished by brake voltage. If the brake voltage is higher than 5V, use the high battery brake, and if the brake voltage is lower than 5V, use the low battery brake. The effect of the high-battery and low-battery brakes is to cut off the power of the brake. First, identify how many wires come out of your brake handle: one for the high-battery brake and two for the low-battery brake. (If your car is a turn brake, you need to pull out the white and black low battery brake and put it together with the turn handle wire to achieve the effect of cutting off the power of the brake). 2. Because EABS electronic brakes are built into the controller program, the electronic brake effect will be generated as long as the brake power is cut off. The electronic brake is activated when the brake power is cut off. The motor generates a reverse force to brake. Sometimes there will be a \"click\" sound, which does not affect the motor. Please feel free to use it.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSTEP 7. 7 Connect the instrument cable\u003c\/p\u003e\n\u003cp\u003eThe instrument cable is a single thin green cable, suitable for pointer instruments.

Among them, the red and black lines of the anti-theft power supply represent the positive and negative poles of the battery, respectively, while the red line of the anti-theft signal is the electric door lock line, the yellow line is the wheel signal line, and the blue line is the anti-theft signal line.
