Why is the electric tricycle not powering on when unlocked?
3 Answers
The reasons for an electric tricycle not powering on when unlocked are as follows: Fuse blown: When the entire electric tricycle loses power, the first consideration should be the fuse issue. If the fuse of the electric tricycle is blown, the entire vehicle will experience a power outage, commonly referred to as not running. For this situation, the repair is actually quite simple—just replace the fuse to resolve the issue of the electric tricycle having no power. Poor contact in the battery internal wiring: Secondly, it is necessary to consider whether the battery is faulty, causing the electric tricycle to lose power. When the internal wiring of the battery becomes loose or corroded, it will manifest as poor contact, leading to a short circuit in the battery and resulting in the entire vehicle losing power. So, how should this be repaired? Open the battery pack and use a multimeter to locate the part with poor contact. If it's just a loose connection, simply reattach it. If it's a corrosion issue, then the wiring needs to be replaced.
I've repaired many electric tricycles, and the issue of no power when turning the key is usually due to a dead battery or wiring problems. First, check the battery level by charging it for an hour with a charger—if the green light comes on, it's fine. If not, the battery terminals might be loose; just tighten the screws. Next, inspect the ignition switch to see if it turns smoothly—if dirty, blow on it to clean. Blown fuses are also common; they're in a small box near the controller—try replacing with a new one. Controller failure can cause a complete power loss and requires professional diagnosis. For maintenance, keep battery terminals clean and avoid water ingress during rain to prevent short circuits. For a cost-effective solution, try replacing the fuse first, or visit a professional shop to test voltage with a multimeter.
My electric tricycle wouldn’t start or power on last week, which was really frustrating. After checking the battery, I realized I had forgotten to charge it. Charging it overnight fixed the issue. Sometimes the battery wires come loose, but simply reconnecting them solves the problem. If the key is old, it might get stuck—just lubricate it or use a spare key. If none of these are the issue, it could be a blown fuse; replacing it with a one-dollar fuse usually does the trick. Once, I had a faulty controller and had to replace it, costing over a hundred yuan. For simple issues, handle them yourself, but if unsure, ask a mechanic—don’t tinker randomly to avoid damaging the circuits. Make charging a habit and check the wiring monthly.
