Open the case, the fuse has burned. High voltage output of the high voltage side of the transformer , the outer and inner insulation paper are bulging opening and carbonized into darkness. Carefully poke charred outer layer. Lead is found in high-voltage and high-voltage transformer welding outer ignition coil shorted , burned coils 1l laps.VXhservice manual download site

The reason is the high-voltage transformer output lead terminal is loose , making the welding transformer too close to the outer coil , high voltage rectifier is connected to the lead and coated with insulating paint on the lead . Insulating paint falling aging , resulting in a move transit , the leads and the coil back and forth friction welding . Damage to the coil insulation. Cause of the failure.VXhservice manual download site

    Approach: removing burnt outer packaging and the inner insulating paper with bamboo ( tip ) to gently pry the coils burned thread , and clean up .VXhservice manual download site

Appeared intact part to the ignition coil by measuring the beginning ( the first transformer core is riveted on the ground ) was slightly lower than normal resistance between 100 ohms , indicating only a short burning , mostly , intact It seems also available. So plus lead solder ' pick firmly , and put insulation coated with insulating paint tube .VXhservice manual download site

While the other was damaged coil without touching poke and insulated handle , remove residue with carbon tetrachloride ( or alcohol ) was washed black carbonized carbon layer , net after washing hands . Bake in the oven for two hours, take the heat insulating paint coated , then bake for one hour, twice repeated baking varnish coating , paint intact upon drying installed . Were tested in various fire place. Boot normally, after six months of work has been normal use .VXhservice manual download site
