1 LED dead light does not light up, you can replace the LED, but pay attention not to reverse the polarity. 2 The lead-acid battery is damaged, resulting in the failure to charge and discharge, and it can only be used after plugging in. 3 The high-voltage step-down capacitor is damaged, or the rectifier diode Overvoltage damage, resulting in failure to charge. At this time, an ordinary pointer-type multimeter can be used to detect and solve the problem. 4. The pull switch is in poor contact or damaged and cannot be turned on.
