Under normal circumstances, the fuse tube fuse tube fuse tube fuse tube fuse tube is the charger internal circuit short circuit or over current fault. This is because the charger for a long time in high voltage, high current state, high failure rate of internal devices. In addition, when the grid voltage fluctuates, the surge causes an instantaneous increase in the current in the charger, resulting in a fuse. The solution: Look at the parts on the board first, see if they’re burned out, or if there’s an electrolyte overflow, and it doesn’t seem to make a difference. Then measure the resistance of the power input. If it is less than 20ok Ω, there is a local short in the back end. Then the forward resistance,
