    I have a picture to show the circuit on my breadboard. I can't seem to get a reading as to the current for the circuit. Do I have it set up right to get the current reading from the DMM. I know it will be a little hard to see in the picture, but I do have all the wires in the right holes and I have checked to make sure that I still have power going through the circuit. Let me know what you guys think. I think I might have blown a fuse in the DMM.

    Your meter appears to be on AC amps? Is that correct?

    Yes, the display says AC. I believe he needs to press the orange button to measure DC.

    That was always getting me on my Fluke. My Agilent meter starts off in DC current though. :)

    sorry for the slow reply, I have been at work. I set up the circuit again and tried to see if it was because I had it set to ac instead of dc. It still didn't work. I forgot that I had another cheap DMM. So i hooked that up and I was able to get a measure.

    I also checked the fuse like KJ6EAD suggested and it is saying that the fuse is blown. Thanks for the help!!

    Unless you are an electrician it would seem logical to start in the DC mode since most electronic voltage measurements involve DC.
