I have a car DVD, Dongfeng Liu steam original, above the red and white three power lines, who can tell me which is a positive pole which is negative?
General red - positive black - negative white - signal
Car DVD power supply three wires red is positive, black is negative, white is the control line.
DVD on the label, display terminal interface definition, each model terminal definitions are not the same, are generally 12V power supply, the current between 1A to 1.5A. Observe the wiring harness of the car and navigator, the thickest black line and the red line are power, and a thinner red line is also connected to the power supply.
