Ok. So I finally got a new volt meter from the one that didn't work (or may have blown with my bad 5v DC transformer).
Anyway it is all hooked up and it won't read correct voltage. It hovers around 0v. I have it wired just like Kal does in his diagram. I have also tried to wire it to the hot and neutral bus for 120v and get the same results. Any suggestions?
Here is a video of the meter in action.
Do a quick test.
Disconnect the 120V from the meter and connect to a 9V battery.
If it shows 9V you have a DC meter.
Your display shows a (-) sign which makes me believe you got a DC Volt meter not an AC.
