Default Problems with test load

Heey,

I am having some problems with my test load for my 660nm diode.
I am useing 3 1N4007 diodes and 1 1ohm 5 watt resistor.
When i measure the voltage at the resistor it gives back 0mV, wich is weird because when i measure the voltage that the driver outputs it gives back the correct voltage.......
I already made a second test load because i thought it might be a broken diode or resistor.

Thanks in advance.

With a round driver the middle circle is battery positive, and the outer ring is negative.
Do you have that right?

Mabye you have the diodes backwards, try fliping them around
