Re: Shortwiring AC/DC power adapter

Wall worts / AC-DC wall adapters: UL listed wall mounted transformers are required to have thermal / current fuses. The thermal / current fuses will fault with excessive temperature or current. The fuses are about the size of a 1/4 watt resistor and may be difficult to locate as they may be placed any where in series with the winding.
In this case, where as the LED is still illuminated, if the transformer is equpped with a fuse, the fuse is still conducting and the source of the failure is most likely the rectifier diode.
As recommended in previous posts, a replacement power source would be the most reliable solution.<p>Ned
