I have a junction box that has power coming into the box (checked with voltmeter) but when connected to any source like a light there is no power to the source. I have connected them properly hot to hot, neutral to neutral and connected them with wire nuts. There is power as far as the connection but then nothing. I also checked the lines using a circuit tester and the lines appear to be fine. It doesn't make any sense that the power would not flow through the join to the connecting wire. Any help would be greatly appreciated.
