FAW Jiefang J6 JH6 DC Electromagnetic Relays LD004 3708020-92W/A21.01.14 24V180A
Key Function
In Jiefang trucks, it is primarily responsible for controlling the connection and disconnection of the main electrical circuit using a low-level control current, while handling high currents of up to 180A. Failure of this component can result in a total loss of vehicle power, incomplete power cutoff, failure of headlights or high-power auxiliary equipment, or even an inability to start the vehicle.
Common Faults
1. Contact Sticking (Stuck-Closed Fault): Due to the extremely high current flowing through the component, arcing may occur at the moment of disconnection. Over time, the internal contacts may fuse together. Even after the key is removed, the vehicle remains powered, leading to battery drain or even wiring overheating.
2. Coil Burnout or Open Circuit (No-Connection Fault): Unstable control voltage can cause the internal coil to overheat and burn out over time. Symptoms include the absence of the distinct "click-clack" engagement sound from the relay when the power switch is engaged or the key is turned, resulting in a complete loss of power to the vehicle.
3. Excessive Contact Resistance: Arcing causes a carbonized layer to form on the contact surfaces; while the relay may still engage, electrical conductivity is impaired. When high current flows, the relay becomes abnormally hot, and downstream electrical components suffer from insufficient voltage (e.g., dim headlights or weak engine cranking).
