ante Posted June 15, 2005 Report Share Posted June 15, 2005 Hi quynh,Welcome to our forum.This could be a hard nut to crack without a circuit diagram. Have you found any broken or burned parts and have you checked the batterys and fuses and so on? Quote Link to comment Share on other sites More sharing options...
quynh0981 Posted June 16, 2005 Author Report Share Posted June 16, 2005 Hi Ante,Thanhk you very much for replying me!I've checked all that, but nothing is strange.

ante Posted June 16, 2005 Report Share Posted June 16, 2005 Hi quynh,I am sorry I don’t have any schematic for this UPS. You could try finding the data sheet for the switch controller and maybe find out something useful from it. Quote Link to comment Share on other sites More sharing options...
