You ARE meaning mA, not mW, correct?

And are you wanting to test for the current it is drawing from your batteries?

Let me know....

Most multi-meters have fused shunts for current measurements. Some have separate input jacks for the probes when measuring current. Your meter probably has a blown fuse or you're not using the right inputs.

I've actually taken pictures of how to measure current on a dorcy jr.

Negative is hooked to the other side of the LED.
