If the diode was shorted, it would have blown the fuse/breaker on the power supply (or melted something else if the supply wasn't protected). If the diode was open, the radio would have worked as normal when the power was connected properly. Neither were the case. True, the diode is not causing the problem he is seeing... but it may well have been damaged at the same time. After finding the O/C problem, he should replace the diode as they are cheap enough - and put a fuse in. Brainbuster. |
