Have you ever experienced any of these problems with your scooter's display? Sometimes the display malfunctions after prolonged use. No matter how hard you try to kick-start it, nothing happens. Sometimes it just starts on its own. Or maybe it is running fine and then suddenly loses power. Yeah, it turns out it is because of this QS-S4 display. People are somewhat divided on it - some think it's convenient, while others find it to be a hassle, especially with the magnets falling off occasionally (though sometimes it's simply an issue with the factory glue). Every product has its quirks, right? After delving into it, we have devised some solutions.
It seems that most electric scooters (we work closely with manufacturers like ZERO 8 , ZERO 9, ZERO 10X , ZERO 11X) use this QS-S4 model (Even though the product is updated in 2024, the new dashboard will continue to utilize the card reader that is previously used in the early version by VSETT. Despite there still being a significant amount of inventory in the market). Upon examining it internally, we discovered that its operational principle is actually quite straightforward. It adjusts the speed by rotating a magnet to change the angle and provide feedback to the signal line connected to the dashboard. If the magnet happens to detach for any reason during this process, there is a high chance that the electric scooter will begin running at its maximum speed. Interestingly, this dashboard design features a substantial portion of the magnet on the exterior, increasing the likelihood (whether due to inadequate adhesive or falling off in a collision) that the magnet could detach and be lost. So how do we fix it? It is simple - get rid of the part completely!
The answer is: Of course!
As shown below, this dial, from the well-established company Five Star, can help us solve the issues mentioned above. We will solder its signal wire to the internal instrument, then remove the plastic part of the dial before QS-S4 as shown in the diagram along with the inside magnetic part. Next, connect this xxx, and then we only need to rotate this part here, and the scooter will start normally. For more details about this dial product, please refer to the following:
