Where is the main relay of Wuling Zhiguang located?

Wuling Zhiguang's main relay is located at the lower left corner of the engine under the hood. Below is more relevant information: 1. Wuling Zhiguang's main relay: The main relay of Wuling Zhiguang has a control system and a controlled system, applied in automatic control circuits. It functions as an 'automatic switch' that uses smaller current and lower voltage to control larger current and higher voltage. In the circuit, it plays roles such as automatic regulation, safety protection, and circuit conversion. 2. Working principle of Wuling Zhiguang's main relay: The main relay is primarily used for overload protection of electrical equipment (mainly motors). It operates based on the principle of current thermal effect and has an inverse time-delay action characteristic similar to the allowable overload characteristics of motors. It is mainly used in conjunction with contactors for overload and phase-failure protection of three-phase asynchronous motors. In actual operation, three-phase asynchronous motors often encounter overcurrent (overload and phase failure) phenomena caused by electrical or mechanical reasons.

As a seasoned mechanic with years of experience repairing various vehicles, I can share the common location of the Wuling Zhiguang's main relay. From my observations, it's typically hidden in the fuse box area within the engine compartment, specifically near the front wheel on the driver's side. After opening the hood, you'll see a rectangular black plastic box; lift the cover to reveal multiple small relays and fuses arranged inside. The main relay is usually the largest one, possibly labeled "Main Relay" or something similar, responsible for controlling the current to the starting system and fuel pump. If it burns out or has poor contact, the car may fail to start or suddenly stall while driving, which is quite dangerous. Always disconnect the battery's negative terminal before inspection to prevent short-circuit risks, then use a multimeter to test for continuity. During routine maintenance, pay attention to moisture and dust prevention to avoid circuit corrosion. Replacing it with an inexpensive relay can solve most starting issues, but make sure it matches the original factory model.

I've been driving my Wuling Zhiguang for several years, and one incident involving a main relay failure left a deep impression on me. In my older model, the main relay was located inside a small compartment beneath the dashboard, just under the steering wheel. Lift that plastic panel, and you'll see a cluster of fuses and relays—the one positioned at the edge or larger in size is the main relay. That time my car wouldn't start, and after troubleshooting, I confirmed the relay contacts had oxidized. Replacing it cost just thirty bucks to fix. DIY is straightforward, but always turn off the engine and disconnect the battery beforehand, maintaining a safe distance. I recommend regular cleaning of this area to prevent dust buildup from affecting performance. Knowing the location of this small component can save you money and avoid the hassle of breaking down on the road.

As an automotive circuit enthusiast, I find locating the Wuling Zhiguang main relay quite interesting. In most models, it's located in the footwell area on the passenger side, concealed within a small box. After removing the plastic cover, you'll see several relays; the main relay is usually distinctive in shape and controls the core power supply to the engine. If it malfunctions, it can easily cause starting failure or unstable driving. When inspecting it yourself, first visually check for any signs of burning or damage, and gently wiggle it if necessary to test its stability. The entire process should be conducted with the engine off and the battery disconnected to ensure safety. For those who enjoy DIY, replacing a relay is an entry-level project that can deepen your understanding of vehicles.
