Reply to "MTH Z 500 Transformer has constant 18 Volt output."

This O Gauge forum has been a great help to me. Lets refer to the Railking Z 1000 controller at this time.. When mine went full voltage I was shown the possible problem. I unsoldered the little culprit, tested it like I do all other diodes and showed faulty as current flowed both ways. As I talked to the person at the electronic store he asked how I tested the diode and he responded that it was normal. He found this item, that he identified from my removed part and said voltage was different but should work and it did work, So the question I have If in fact it is a diode why does it test faulty? If is not a diode what in the blank blank is it called and how can it be tested removed? As I previously stated I am not a electronics brain by any stretch! I want go give special thanks to GG as he has bailed me out more than once, also many other people on this forum. Special thanks to all from a grateful old man. God Bless Roy O
