My friend accidently stepped on a wire for his light and the tension broke the adapter's connector - I told him I'd try to fix it. I've already cut the connector off and have readied my replacement. I plan to use solderless connectors but as the original connector colors are unfamiliar I want to check with this site about how to check for which wire is power and which is ground.
Can I use my multimeter to check which wire is power and which is ground? If so what setting do I need to use?
