Both the 2 different kind of diodes I have do have readings in both directions but the diode I took out of the set was the same as others i have, red band, and that one only had a reading in one direction, the extra red band diodes i have all have readings in both directions and the diode I took out of the set came from the extras, they're all the same. I kind of wonder I have a SAMs and it shows the cathode end of the diode facing up maybe it's a typo the way SAMs has mistakes but I didn't try the diode the other way. Is it possible the diode would work the other way around. I don't have another schematic to rule out the correct diode position .
