Don’t laugh at me, but i don’t know which setting on my multimeter to use. I wasn’t getting anything when I tried. This is the one I have if you wouldn’t mind letting me know which setting to use (and where to touch the red and black pins too?): https://www.amazon.com/dp/B01ISAMUA6?ref=ppx_pop_mob_ap_share
