BRIAN LIFE AND TECH

Hi all, for the past 14 months, I have been travel long distance around 160+km go to office and back.  Every month, average distance around 3000km and I am using my CT100 for that travel,most of the time.

Figure 2: Two of broken capacitor Figure above shows internal component of charger. input supply are from left side which will pass through some important component like rectifier, capacitors, inductors and transformer (part of converter and filter). AC supply power are converted to DC supply that

Hi, my wife complaint lately about our water kettle not working. this is second kettle having the same problem... I realised that two of my water kettle with new base design having the similar problem, which are its live metal connector, that supply power to the kettle, changing its colour and corroded due to high current flow.  Due to high current flow, live cable seem to be overheat causing some plastic around it melt.

Figure 3: unscrew the bottow base to access the internal part of base. and most of the time, causing the plastic around the cable melting and ending up open circuit to the kettle which lead to unworking kettle. Figure 4: It was found that life connector and plastic holder around it have been damaged due to overheat. What I did is disassemble the kettle base..and find th
