Jinbei Haise's fuel pump relay and main relay along with the fuse are located in the battery box under the driver's seat. The working principle of the fuel pump relay is as follows: 1. Principle One: When the relay operates, the electromagnet is energized, pulling the armature down to make contact between D and E, thereby closing the working circuit. When the electromagnet is de-energized, it loses its magnetism, and the spring pulls the armature up, cutting off the working circuit. Thus, the relay uses the electromagnet to control the on-off switch of the working circuit. 2. Principle Two: Electromagnetic relays generally consist of an iron core, coil, armature, and contact springs. When a certain voltage is applied across the coil, a certain current flows through it, generating an electromagnetic effect. The armature then overcomes the force due to electromagnetic attraction. 3. Principle Three: The return spring's tension pulls the armature toward the iron core, causing the moving contact of the armature to engage with the stationary contact (normally open contact). 4. Principle Four: When the coil is de-energized, the electromagnetic attraction disappears, and the armature returns to its original position under the spring's counterforce, causing the moving contact to re-engage with the original stationary contact (normally closed contact).

When it comes to the location of the fuel pump fuse in the Jinbei Haise, it's located in the fuse box near the driver's left knee. Open the small cover under the dashboard, and you'll find multiple fuse slots. The one for the fuel pump is usually labeled 'Fuel Pump' and is positioned roughly in the middle towards the top. If the labels are unclear, refer to the vehicle manual for the specific layout, as it provides detailed labeling. It's advisable to turn off the ignition before handling to avoid short circuits. Common causes of blown fuses include voltage fluctuations or aging wiring, so keeping spare fuses of the same amperage on hand is practical. If a fuse is blown, simply replace it, but if fuses blow frequently, inspect the fuel pump or electrical system promptly to avoid breakdowns on the road.

My Jinbei Haise also had a fuel pump fuse issue before. It's located in the fuse box on the left side of the dashboard. Lift the plastic cover near the driver's legs to see it - the fuse position is near the top slot marked with a fuel symbol. If you can't find it, the manual is your best helper. Fuses often blow due to circuit shorts or overload, like worn wiring. I usually replace it with a new fuse to test - if it blows again, check for abnormal noises from the fuel pump. Keeping spare parts is wise for quick fixes in similar situations.

When I first learned to deal with the fuses of the Jinbei Haise, I was told that the fuel pump fuse is located in the box under the dashboard. Open the cover next to the driver's seat, and you'll find a small card with labels indicating the fuel pump position—it's in the upper middle section. If it blows, the car might not start, but you can simply replace it with a spare fuse—it's an easy operation. Just remember to turn off the engine before you start.
