Why is the odometer of the Jog i not working?

The main reasons why the odometer of the Jog i is not working are as follows: Odometer soft core disconnected: This refers to the connection device between the transmission and the odometer. It may be that the core in the middle is disconnected. If it is not broken upon inspection, then check the speedometer gear on the transmission for any faults. If it still doesn't work, replace the speedometer. Loose plug: As well as a circuit break, both can cause the speedometer and odometer to stop working. The user can simply secure the plug. Disconnect the sensor connector, turn on the ignition switch, and the 2nd electrode in the connector is connected to the brown background with red stripes. Use a self-made wire with a plug to extend and lightly touch the grounding part of the vehicle body to input a pulse signal to the instrument. If the speedometer needle moves at this time, it means the instrument is normal, and the fault lies in the sensor reed switch tube or magnetic ring.
The odometer on the Jog-i isn't moving, most likely due to a drive chain issue. I've fixed several bikes with this problem before - usually it's either a loose chain or a complete break. This bike's odometer relies on the front wheel sensor for signal transmission; when the chain breaks, the sensor loses signal. Another common issue is water ingress and rust in the sensor connector, especially after riding in the rain. The most troublesome scenario is a burnt instrument cluster circuit board - last year I encountered a modified bike where improper lighting installation caused a short circuit in the dashboard. I'd suggest first checking if the cables near the front wheel bearing are worn through, then use a multimeter to measure the sensor voltage. Don't rush to replace the entire instrument cluster - checking these areas first could save you significant money.
I know exactly how frustrating a stuck odometer can be. Just last week, I helped a neighbor fix the same issue on their Jog-i. Turns out, the magnetic sensor in the front wheel bearing was clogged with metal shavings. Scooter front wheels tend to collect a lot of dirt and debris, and metal particles get attracted to the magnet—cleaning it out did the trick. Another possibility is excessive gap between the sensor and gear assembly; just adjust it with a thin washer. The craziest case I've seen was when a high-pressure car wash loosened the instrument cluster connector. Quick tip: if the dashboard backlight is on but the odometer isn't moving, you can pretty much rule out a fuse issue. And remember to wear anti-static gloves when handling electronic components—they're quite delicate.
