    I've been told I need to wire the multimeter in series with the LED I'm trying to measure. I tried doing that and now the COB won't power on. I made a diagram for the wiring when I initially successfully wired up the LED so I'll post a picture of that below along with pictures of my wiring.

    Diagram: Imgur: The most awesome images on the Internet -

    Any help would be greatly appreciated.

    Edit: Also going to add a picture of the diagram I'm trying to replicate.

    If the COB does not work when the meter is removed there is a circuit fault, if it is only when the meter is in place then a fuse may have gone in the meter, the start up current can be quite high on LEDs and the meter may not be rated for that.
