question 1: there are three wires on the motor of my range hood. how to connect them? If there are three wires, then there are two power wires, one is a ground wire, and the yellow-green wire is a ground wire. It is best to read the wiring diagram on the drawing clearly, so that there will be no mistakes.

Question 2: How can a smoking machine with three wires and capacitors be connected to a power supply? Red (because the motor is different in color), gray or white is connected to the capacitor, and yellow or blue is connected to the capacitor and power supply. There is a sign on the general motor

Question 3: How to connect the wiring of the range hood to the four wires of the motor and the four wires of the switch to the three wires of the power supply? One end of the switch is connected to the live wire, and the other end controls the motor respectively, so as to illuminate

. Question 4: Connection method of the motor (with three leads) and capacitor of the exhaust fan and hood. Measure the resistance of the three leads with a multimeter, with two leads with larger resistance connected to the capacitor and the one with smaller resistance connected to the power supply, as shown in the figure: hi.baidu/...#

. Question 5: Connection method of the capacitor of the three-wire hood motor. Do you have a multimeter? Generally, you measure which pair of wires are connected and which pair has the largest resistance. One of the pair with large resistance is connected to the capacitor "Capacitance Only". Then add another one with a large electric foundation and one with a small resistance and a power cord. The remaining one with low resistance is connected to the power line. Plug in the power, and if the wind turns in the opposite direction, just switch the first capacitor with the other end of it and then connect it as before.

question 6: how to buy a three-core cable when the three wires of the lampblack machine plug are extended, and then cut the original cable (in case of power failure) and connect the new cable in the middle, just one-to-one correspondence. Don't forget that the wire connector should be insulated.

Question 7: How to connect the wiring of the smoke machine with the wiring? There should be three wires when cutting the wiring of the smoke machine, among which the yellow-green one is the ground wire to connect the two live wires and the zero wire of the power supply. If you connect with the wiring, there will be only zero and no ground wire, so that the smoke machine can work, but once the smoke machine is exposed, there is no danger of grounding.

Question 8: How to connect the five wires of the hood motor? Problem: There are two red lines on the original machine. The red line is the same. The remaining three best answers are white, yellow and blue: two red lines start capacitors at both ends, and the remaining three gears are white, yellow and blue. To measure the resistance of each winding with a multimeter, the maximum resistance is the total resistance of the starting winding and the running winding. Then, take any lead with one stylus and find the center tapped lead with the other stylus. The organization of the center tapped lead is about half of the total resistance. Then one stylus taps the center of the tower, and the other stylus looks for the third tap. In general, the resistance of capacitor-started motor winding is greater than that of running winding. Specific to the hood motor you mentioned, the biggest possibility is that two red wires have total windings at both ends, and the remaining three wires, white, yellow and blue, are three central taps with different resistance values for speed regulation, and different resistance values control different motor speeds.

question 9: the wiring of the smoking machine is all messed up. how to connect it? the more detailed it is, the better. 31 minutes, you will combine one wiring of the two motor lines, one wiring of the lighting lamp and connect it with the motor line. Connect a switch. Just connect the outlet to the plug.

Question 11: The smoking machine used to be a plug. Now, how to connect the switch and cut off the plug? There are three wires, one blue wire is directly connected to one end of the power supply, the other red wire is connected to the switch and screwed, and the other screw is screwed to one wire of the power supply. The other yellow thread need not be wrapped.
