While installing my Dynojet WBC, I wanted to tap into the wiring coming off the back of the head light switch. My manual said the purple/yellow was the correct wire for the gauge. But when I grounded the wire with my test light, all of the gauge lights went out until I removed the tester from the wire. I’m sure I have the correct wire but I’m unsure why all of the lights went out went I tried to test the line. What gives?
