The fault is mainly is caused by the damage of charging circuit. Because the light is not bright, so the power switch failure or charging circuit solder joints or most likely to break, should first check the solder joints on printed circuit board and cables for release, if there is a burning and fracture damage components. Some razor charging circuit set the temperature fuse tube, should check whether the fuse. If yes, can exchange, also can it short circuit when emergency repair, but after their make-up fuse tube. If the above check didn't find any problems, check the charging circuit components, usually in resistance, the damage of the transformer and the transistor to see.EMHservice manual download site
