Motorcycle clever plug-in switching lighting circuit

Motorcycle cleverly adds a relay to switch the speaker of the lighting circuit motorcycle, the brake light, the brake light is generally powered by the relay GB, while the headlight H1, taillights H2, nightlight H3, etc. are powered by the magnetoal motor GS, see Figure 4-54 (A). Therefore, when the motorcycle engine is stopped, these lights are off, and there is no parking sign when parking at night. In order to overcome the above drawbacks, the circuit has been changed. A relay is added to stop the parking and the engine. When the battery is powered, the taillights and nightlights are powered by the battery, and the engine can still be powered by the magnetoal motor GS after the engine, and the circuit is shown in Figure 4-54 (b). In Magnetoelectric GS The output is connected to a diode VD2, and its rectifier voltage is supplied with a capacitor, and a working current is provided for the relay K after C filter. Motorcycle starts, when the GS output voltage, K is bonded, its contact action, 1, 2 on, large light H2, taillights H2, the night light H3 is powered by GS; when the generator is parked, K lost current voltage However, the battery GB does not provide a power source for K by the VD1 reverse cutoff, so the relay k is released, and the contact can restore the normally closed state, 2, 3 turned on, the battery GB provides power supply for H1 ~ H3. S1, S2, S3 are headlight switches, tail light switches, and night line light switches. Component selection: Vd1 with 2 cp1 or 1 N4001; C with CD11-25V-220μF electrolytic capacitor; K with J2X-2F small medium power relay, the coil rated voltage is adjusted to the motorcycle. Contact can be used in parallel to increase the contact capacity.
