If you have an ohm meter, connect the red wire to the pos. on the meter, and the black wire to the neg on the meter. You should show no continuity. Reverse the wires and you should have continuity. Probably somewhere around 4 to 8 ohms. If you have no continuity either way, there is a break in the wire or the diode is blown. If you have continuity both ways, the diode is shorted.
