To measure current, your multimeter should complete the circuit, right?

I don't know why I'm failing so badly today, but I can't seem to get a reading...

what am I doing wrong?

the driver is set to output 3v, and it works fine if I short the multimeter out of the circuit...

yes, I've tried changing the polarity of the multimeter

Most meters have a fuse in there -- did you blow it up ??

Good call!

I never would have thought about that... it was indeed, blown.

I went and replaced the fuse with a length of wire, (I could stand to buy a better meter anyway...) and it's measuring current just fine now... Thanks!
