So I need to check the wiring to my circuit board with the r.s.r logic probe and pulser... Can't go above 5v or I will mess up the chips. I was told about a truck I can do to test the levels at home... Get a 5v wall charger and cut it to expose the wires and connect them the probe.. But I have to wire to right to not mess up the board or not cause a fire lol....
I cut open a old charger that read Input: 100-240VAC output: 5vDC .. And I don't know which side is the negative or positive side..... I only know u connect red to red and black to black... But the wires inside are brown... Not red and black..... Any pointers??
