Why is the dashboard of an electric tricycle not lighting up?

There are three reasons why the dashboard of an electric tricycle does not light up. Motor damage: When opening the motor, be careful not to let the motor windings rub to avoid damaging them, and do not use iron objects to hit the magnets to prevent them from cracking. When replacing the Hall sensor in a brushless motor, pay attention to the connection of the Hall wires. If it's your first time, it's best to remove one wire and solder the new one to avoid incorrect soldering. After soldering, first use 502 glue to secure it, then use AB glue to reinforce it to prevent loosening. When replacing magnets, ensure that the glue on the stator and magnets is cleaned off. When gluing magnets, apply glue to the opposite side of where the magnets attract each other, then bond them. Dashboard circuit damage: If the power indicator light on the electric tricycle dashboard does not light up but the motor runs normally, it could be due to no voltage between the positive and negative leads of the dashboard, poor contact in the connectors, or broken leads. Simply reconnecting or replacing the wires should resolve the issue. LED damage: When the LED on the electric tricycle is damaged, it needs to be replaced or repaired. If there is a break in the dashboard circuit board, promptly replace or repair the dashboard circuit board.
When repairing electric tricycles, I often encounter issues with the dashboard not lighting up, mostly due to a blown fuse. The circuit overload protection causes it to burn black. You can start by checking the fuse box, usually located near the battery, and use a multimeter to test the voltage. If the voltage is normal but the dashboard still doesn't light up, there might be loose wiring or a faulty dashboard itself, which requires opening the panel to inspect the connections. Battery aging is another common cause; when there's no power, the entire system shuts down, and the dashboard goes off—try charging it. Regularly inspect the wiring and fuses to prevent rainwater from corroding the circuits. Addressing these issues in advance can save you from panicking while driving.
I once had an issue with my electric tricycle where the dashboard wouldn't light up, which really freaked me out thinking it would cost a fortune to fix. Turned out it was just a blown fuse - replaced it with a new one and the lights came back on. Poor battery condition often causes this too; old batteries can't hold charge well, leading to unstable power supply to the dashboard and resulting in blackouts, which usually recover after charging. A simple troubleshooting method is to first test the system power by turning on the headlights, then check the dashboard fuse in the fuse box to see if it's intact. If you have the tools, you can replace the fuse yourself; otherwise, just visit a nearby repair shop - it's a quick fix. For daily use, pay attention to your battery's lifespan and avoid waiting until it's completely drained before recharging.
