The connection of the relay, two copper wiring terminal, a head is connected with the battery positive electrode (red line), another head is connected with a starting motor body screw; relay with thin, green line to connect the battery negative electrode, yellow red line meets the right hand to start button switch out of Huang Hongxian (shall not be connected in the switch lock out of the black line)

Relay common fault:

1, the electric start switch contact is bad, the motorcycle fault phenomenon is unable to start.

2, the stall switch circuit, the motorcycle can not start after the file.

3, the switch of the use of the switch in the starting switch circuit in the diode, if the diode is broken, the electric switch is stuck, the motorcycle can not control the electric circuit.

4, relay coil iron core and two connected electric string stick, create the illusion of engine can not put out the fire, in fact, is after the closing of the relay does not release caused by starting the motor has been at work, this time to quickly cut off the power supply, so as not to damage the electric starting line of electrical equipment.

The relay is an important function of the motorcycle, which is an electric appliance that makes the current pass through. Usually placed in the electric circuit of the motorcycle, it is composed of a coil, a movable core and two terminal, and a power cord, a power switch, a diode and a starting motor (motor) are connected in series to the electric starting circuit of the motorcycle.

Relay working principle: turn on the switch lock button of the electric starter button switch, relay coil energized, according to the principle of magnetic induction coil learns the electric coil produces a magnetic field, iron core coil into the magnetizer and relay is connected with the two connecting column to the electric starter motor is energized, thereby triggering start motor rotates and drives the engine ignition, reach the goal of starting a motorcycle.
