During the daily use of electric tricycles, there may be some unusual problems. For example, we found that the fuse of the electric tricycle burned continuously. How did this happen? Let's take a look at some specific reasons.
Based on the previous experience, this situation can be summarized for several reasons: 1. The controller is damaged; 2. Instrument short circuit; 3. Short circuit of lamp holder; 4. Broken wires and short circuit; 5. The battery is negatively connected. Of course, there may be other reasons in real life.
Then, for different reasons of failure, we need to take appropriate measures to deal with it. First, we need to be specific. At this time, we should first cut off the electric tricycle battery plug, switch and open switch, then turn off the switch of all lamps and lanterns, multimeter electric block is used to measure the resistance between plug.
If detected, the resistance is found to be very small, even close to zero, which means that there is a short-circuit problem. Then by breaking the method to detect the specific position, this time should cut off the power supply of the electric tricycle controller, and if the electrical signal is restored to normal, the controller will be damaged.
Otherwise, the explanation is other. For example, if the headlights of the electric tricycle are turned on or the fuse is turned on, it should be checked whether there is a short circuit in the headlamp holder and the steering lamp holder. Then adjust according to specific situation.
In conclusion, we need to find out the reason and then fix it so that the electric tricycle can get back to normal, so as to ensure the safety of the user.
