Thanks for explaining your process. I will test mine and see what I learn.
I wish I could help you with your issue. My only guess would be maybe the LEDs don’t draw enough current to cycle the flasher. Have you tried swapping in some none LED lights to see if the hazards would work then...
@archie73 I am trying to trouble/test my hazard switch, the same switch you posted above. I can’t figure out how it is wired or functions. Could you translate your drawing testing process for this switch. I am still learning as I try to wire my project.
