The hazard warning light can be used when the engine is not working. At this time, there is no need to turn on the ignition system and the instrument warning light. For this purpose, a hazard warning switch is provided. It is a multi-tool linkage switch. When the ignition switch is disconnected, it is turned on Battery wiring, flasher and bulb power are directly from the battery, and the output of the flasher relay is connected with the left and right turn signals. That is, when the flashing relay operates, the left and right turn signals and indicator lights simultaneously send out danger signals.
Prepare the circuit schematic diagram of the model to be connected. If there is no circuit diagram, it is best to draw a wiring sketch by yourself, which will bring great convenience to the wiring maintenance work.
Temporary external wiring is required for maintenance, and insulation must be paid attention to to prevent short circuit.
Do not connect live wires. When the wire is damaged, replace it with a wire of the original standard type. The connection must be reliable and the contact resistance at the connection should be reduced as much as possible.
After the wiring is completed, it should be bound according to the original wiring requirements.
