Although the electric vehicle travel is convenient, but, also can often appear all sorts of problems. Such as speaker function failure, headlights can not be turned on and so on. How to deal with this situation? Below, tianjin electric tricycle for you in detail.
Tianjin electric tricycle, when the electric tricycle problems, we must not panic, to find the right way to deal with. In the meantime, it can be handled according to the following introduction.
How to deal with the situation of electric vehicles:
1. If the single horn function fails, first use the multimeter to test whether there is any current output when pressing the switch. If the current output is normal, the connection of the hardware terminal is bad or damaged. The connection can be strengthened or the hardware can be replaced. If there is no current output. Means that the function switch is damaged or the horn 12V negative line falls off or contact is bad. Replace the function switch or connect the 12V negative wire.
2. Turn on the headlight, which causes other functions to be unable to be used normally or causes a single function to be unable to be applied normally, and turn off the headlight and other functions to return to normal, then we need to choose the maintenance mode where the minority is subordinate to the majority. Bright lights, for instance, affects the other functions cannot be used normally, so, now we need to do is to give headlight establish a separate current lines (generally choose the 12 v negative line), that is to say, need to separate from the battery connected to a 12 v negative thread (remember, the new 12 v negative line also needs to take the same diode, and only with the original 12 v negative line not in series, in parallel to a single power supply line), it can. If only one of these is affected, for example, only the speaker is affected, then the individual current line we need to build is given to the speaker instead of the headlight. This method must be used flexibly, must not choose the majority obey the minority maintenance.
3. Turn on the unilateral turn light, and the other side or other functions are also activated at the same time, or the functions are misaligned (for example, turn on the headlight, the headlight is not on, but the horn is sounded). In case of such a problem, we need to check whether the function lines are stuck together or a short circuit occurs in one of the function lines. This kind of problem usually appears in the function switch wiring block or the function switch wiring block is out of place, open the wiring block to adjust or replace the function switch. If the first problem of example 3 occurs, the dislocation of the function line of the taillight wiring block cannot be excluded.
