I did a diode test on a 1n914. I got 675 with the neg probe on the black band end, and the pos probe on the other end. Reversed them and got no reading.
Does this mean that the band is the neg end? cuz I had it toward the pos end on my rfid system and now it is stuck on. Don't need the fob anymore to activate it. I am told putting the protection diode in backwards can short the module and fry the output keeping it on.
