Dead light

[Darren Hayward]

My Cube has an AXA CL20-E wired in LED light . The plastic mount broke and I've now replaced it and remounted the light, which does not work.
I've bought a multimeter and run a few tests. The wires to the light show 13.8 volts (light is rated 6v to 12v) so there is power.
I've tried to test the light itself. The light doesn't register any ohms (the meter stays on the default reading of 1). Am I testing the light correctly? Or is Ohms the wrong test? And I assume no reading means the LED's are blown?

It's been 40 years since I used a multimeter so it's possible I'm talking out my rear.

Hi
you don't test Diodes with ohms
you need a multimeter with a diode test function


Just had a look on line for you and this explains it and saves me writing it out

How to Test LED Lights with a Multimeter

After learning about the basic details of an LED, the next step for any aspiring robot or electronic circuit builder is to learn about how to test an LED, which is much the same as the method used to test any diode with a multimeter. For this, one requires a multimeter, and of course, the LED to...
