    How Does The Car Starter Extend Life? -Jump Start Manufacturers
    Failure phenomenon:

      1. After the start switch is turned on, the starter rotates at a high speed and the engine crankshaft does not respond. This phenomenon indicates that the fault occurred on the transmission mechanism of the starter, which may be caused by the wear of the transmission gear or the one-way clutch.

      2. The starter does not work properly and the drive gear does not rotate. There are many reasons for this, such as problems with the power cord, ablation of the starter switch contactor, and excessive engine resistance.

      3. The starter has insufficient power output and cannot drive the crankshaft. Short circuit of the excitation coil and loss of the battery can cause the starter to run out of power.

      4. The starter sounds harsh. This may be caused by a one-way clutch jam or improper starter installation.

      5. There is a "beep" sound when the starter switch is turned on, but it does not work. This can be caused by keeping the coil disconnected or the battery being seriously depleted.

      Maintenance advice:

      The starter is a valuable part of the car and is easily damaged, but in order to extend the life of the starter, proper use is also required. In the process of starting the engine, the starter should introduce 300~400 Ah from the battery. Therefore, in order to prevent the battery from overcurrent or damage, the starting time should not exceed 5 s; in winter, it is easy to start difficult. Each start-up time should not be too long at the start, and appropriate intervals should be left in each start.

      Car starter use trouble, please consult the jump start manufacturers

    Emergency Power Check Precautions - Emergency light Manufacturer Carefully Tells You
    The emergency power supply transformer has a short circuit, open circuit, and poor wire insulation.
    When the transformer fails, it should be checked and replaced in time, especially the emergency power transformer, smell, smoke, output voltage is reduced, and the temperature is very fast. The emergency power supply should be cut off to find out the problem. What are the methods for detecting emergency power transformers?
    1) Detecting the turning on and off of the first and second windings, the multimeter is placed in the Rx1 block, and the two test leads are respectively wound by two leads, and the resistance is usually tens to hundreds of ohms. If it is zero resistance, it is short circuit. The same method is used to measure the resistance of the secondary winding, typically tens of ohms (step-down transformer). If there are multiple secondary windings, the smaller the output voltage, the smaller the resistance; the coil is disconnected, there is no voltage output, the outer bow wire is broken, the lead and solder are soldered, and the interior is wet after chrome plating.
    2) Detect windings, windings and core insulation resistance multimeters placed on the Rx1Ok block, one pen connected to one winding lead and the other connected to the secondary winding lead. The multimeter indicates that if it is less than this value, the resistance should be this value. , indicating poor insulation performance, especially when the resistance is less than a few hundred ohms, indicating a short circuit between the windings.
    Using the above method, then continue to detect the insulation between the winding and the core resistance (one test lead followed by the core and the other write the pen to remove the winding bend exit).
    3) If the emergency power transformer emits a "beep" sound, you can press the transformer coil. If the “click” sound disappears immediately, it means that the transformer core or coil is loose, which may be a fixed position where the transformer is loose.
    4) Test the transformer secondary winding no-load voltage Transformer transformer Once connected to the 220V emergency power supply, put the multimeter into the AC voltage module, select the multimeter range according to the nominal value of the transformer secondary winding, and then the two no load voltage. For the secondary winding, the allowable error should not exceed 5%-10% of the normal value (in the case of a winding voltage of 220V).
    If the secondary voltage increases, it indicates that there is a partial short circuit fault in the winding. If the secondary winding of the coil voltage is low, it indicates that the coil is shorted.
