How do I use a multimeter to test LED connections or any others?

How do I use a multimeter to test LED connections or any others? Please tell me like I am a 5th grader . . .or even a 1st grader.

 

THANK YOU!

 

This is what I am trying to test (The solder free connections have a small hole on top to test) --->>>

Diodes only conduct electricity in one direction. Some meters supply enough electricity (when measuring ohms) to very dimly light the LED (ligher emitting diode). So if it does not light in one direction try reversing where the leads are. If this does not work get 2 AA batteries and they should make the LED light. Once you get the LED to light you can move the connection off the pads and to the holes in the connector if that works try the holes at the other end of the wire. So you test wire->connection->led->connection->wire.

 

Does your meter have a diode check function?

Yes

That should light the LED in one direction and not the other. Does it?

Check out my build thread. It works now. The starboard was marked wrong on a single LED. It had + where the - should have been on all three spots . . . o well. Mistakes happen, and it works now. Multimeter was key!!!
