Where is the motorcycle starter relay installed

Relays: As the name suggests, relays are appliances that continue to let current through. It is usually placed in the electric start circuit of the motorcycle, which is composed of a coil, a movable iron core and two binding posts, and the fire wire, electric start switch, diode and starting motor of the electric door lock are connected in series on the electric start circuit of the motorcycle.

The working principle of the relay: open the electric door lock and press the electric start switch, the coil in the relay is energized, according to the magnetic induction principle of the energized coil, the energized coil produces a magnetic field, and the iron core in the coil becomes a magnet conductor and the two binding posts on the relay are connected to energize the starting motor, so as to achieve the purpose of starting the motorcycle.

Common Relay Faults:

1. The contact of the electric start switch is poor, and the fault phenomenon of the motorcycle cannot be started.

2. The gear switch is broken, and the motorcycle cannot be started after being put into gear.

3. The diode is placed in the starting switch circuit by using the switching property of the diode, if the diode is broken, the electric start switch is glued, and the motorcycle cannot control the electric start circuit.

4. The iron core in the relay coil is bonded with the two connecting columns, which damages the electrical equipment on the electric start line.

Relay troubleshooting: First, cut off the power line on the relay, and then check the electrical appliances on its circuit.

If it's a pull cylinder.

Kicking and not moving has nothing to do with the relay, it may be that your car is short of oil and sticky to the cylinder! Or maybe the connecting rod and piston pins are falling off and getting stuck! It is recommended that you go to the maintenance department to check the repair.

Teach you the easiest and most effective way to find the relay: you can find it along the positive pole of the battery (big red line), it is connected to the positive pole of the battery! Specifically, it varies depending on the model! Hope it helps!

The thick 2 wires of the motorcycle starting relay are directly connected to the positive pole of the battery at one end and the starting motor at the other end.

The thin 2 wires can be divided into positive and negative, one is connected to the brake light outlet (positive pole) and the other is connected to the start button (negative pole).

To disassemble the motorcycle relay, the upper cover should be pried open and soldered with an electric soldering ironThyristorsFoot. Wear gloves on your left hand to prevent itBurns, blow the hair dryer on the top setting to the bottom of the product for 10 seconds. When the blow is almost complete, use another wordScrewdriversPry open, the position is the gap between the base plate and the plastic mold.

The function of the motorcycle relay is to connect the battery and the starting motor, when pressing the electric start switch, the current of the battery is sent to the starting motor, the starting motor rotates to drive the engine to start, and after the electric start switch is released, the starting motor is powered off and stops rotating. Relay is a kind of electrical control device, which is an electrical appliance that undergoes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity reaches the specified level.

A relay is a device that is often used as a switch in a circuit. According to the type of control bucket voltage required by its coil, it can be divided into AC relay and DC relay. The specifications of the relay are expressed in terms of coil control voltage and contact current, and usually the load current is less than 10A, and the circuit can be turned on or off directly with the relay's Xiaono Mo contact.

Motorcycle horn plus relay is to let the power of the horn directly from the battery** through the relay, which will increase the loudness of the horn.

Dust destruction reduces the load of the vehicle line, and the specific operation steps are as follows:

1. Connect one of the wires of the horn to the power output cable of the relay.

2. Connect the original car speaker wire to the relay control line.

3. Connect another original car horn cable to another relay control cable.

4. The remaining wire of the horn is connected to the negative pole of the battery.

5. The remaining wire of the relay is connected to the positive pole of the battery of Yutong.

6. Press the horn to open the envy and open the open and it will be used normally.

The motorcycle starting relay is installed in the motorcycle electric start circuit. The main function of the starting relay in the finished vehicle is to control the rotation of the motor in a small current control and high current mode, so as to drive the rotor of the magneto inside the generator to rotate, input the ignition pulse signal to the igniter, make the igniter produce an electric spark, ignite the mixed gas in the cylinder and do work.

Advantages: The electric start system (battery, starting relay, starting motor) is used to replace the original foot start mode, which is labor-saving, easy to operate.

Just look for it along the positive electrode of the battery (big red line), which is connected to the positive electrode of the battery.

Start the key, turn on the starting relay power supply, the relay pick-up is connected to the starter power supply, and after the start-up gear is engaged, the starter rotates to drive the flywheel to rotate and start the engine.

After the engine starts, release the key, the starter power supply is disconnected, and the starting gear is detached from the flywheel under the action of the return spring. Complete the startup action.

Motorcycle Relays: As the name suggests, relays are electrical appliances that continue to let current through. It is usually placed in the electric start circuit of the motorcycle. Just look for it along the positive electrode of the battery (big red line), which is connected to the positive electrode of the battery.

Generally, next to the side battery under the seat cushion, the motor cable is connected to it, which is half the size of a fist.

The scooter is generally visible with the seat cushion removed, on the frame above the rear wheels.

Pictured here is a motorcycle fuse that has been corroded by battery fluid. It must be completely replaced.

The red circle in the figure is the output insurance of the motorcycle battery. There should be a fuse box on the outside of this insurance. This state is insured and damaged only the insurance connection remains.

You can go to a motorcycle repair shop and buy a safety box. It's about two dollars a piece. There is a common insurance policy inside, as well as a backup insurance.

The fuse is used to protect the circuit of the whole vehicle. Prevent the motorcycle from catching fire due to electrical circuits.

Motorcycle horn plus relay is to let the power of the horn directly from the battery ** through the relay, which will increase the loudness of the horn and reduce the load of the vehicle line, the specific operation steps are as follows:

1. Connect one of the wires of the horn to the power output cable of the relay.

2. Connect the original car speaker wire to the relay control line.

3. Connect another original car horn cable to another relay control cable.

4. The remaining wire of the horn is connected to the negative pole of the battery.

5. The remaining wire of the relay is connected to the positive pole of the battery.

6. Press the horn switch to use it normally.

H: Pick up the horn.

B: Connect the battery.

S: Pick up the button.

At this time, the horn is not controlled by the ignition lock. However, at this time, a high-power horn can be used, which can effectively reduce the line loss and protect the ignition lock contacts and button contacts.

If B is connected to the power supply controlled by the ignition lock, the common car is the black wire of the original horn plug, which can only reduce part of the wire loss and protect the horn button.

85 and 86 are the magnetic field coils in the relay, they generate a magnetic force when energized, so that 30 and 87 are closed and on, and 30 and 87 are the switches in the relay.

Let's do it: 30 and 85 are connected in parallel to the positive power supply, 86 is connected to the horn switch, the other end of the horn switch is connected to the negative power supply or tie iron, 87 is connected to one of the wires of the snail horn, and the other is connected to the ground or tie iron.
