That's actually really confusing.
Can you explain that again please?
All I can think of is the LED is acting as it should, a diode.
But as I couldn't decipher your question, or where you are probing, it's just a guess.
EDIT: LEDs don't have positive and negative legs.

That will measure the resistor only.I put the black probe from my meter in the negative power rail. I put the red probe in the hole on the negative led leg
Now with the black lead still on the negative power rail if I place the red probe on the positive side of the circuit on the other leg of the resistor my meter reads 00.0 which means there is continuity, but I was wondering why it would not read .474 ohms like the positive side did.
Are you measuring Ohms on a powered circuit? That is a no-no.

That never even crossed my mind. Well spotted.Are you measuring Ohms on a powered circuit? That is a no-no.

Why do you say it is a dead short? Isn't 00.0 on the ohm setting meaning continuity? Also there is no power going to this breadboard.Ok we got there in the end.
What you are reading is perfectly normal. You are measuring the resistor. Then you are just probing a wire between the resistor and power source, it's a dead short for the DMM.
Martin
Ok so here is where I am confused. Why am I getting a good resistor reading .474 ohms only on one side of the resistor, if the resistor is the bridge to complete the circuit?Yes, continuity means a loop without a break.
What you are doing *is* just putting the meter probes together.
Martin
Yes but I don't see "understand" where I have a break. Why is the resistor braking my path?![]()
This Is continuity.
Martin
So in my case it would be electrically connected, right? I mean the circuit works when I apply powerYou don't have a break. You have very low Ohms reading. A short Or a link or electrically connected.
