I did not measure them as I do not no how to do that. I am just assuming they are shot since so many of the leds were burnt out. The leds that the resistors are attached to are not working, I did try those.

The only tool I have is a 7 function digital multimeter from harbor freight.. https://www.harborfreight.com/7-function-digital-multimeter-63759.html

Is this the tool to use to test them?
