Bought this voltage meter about 6 months ago and it worked fine for about 4 months and then went blank. I checked the connections on the back and where it is wired to which is the main meter on the left. positive to positive and ground to ground. I redid all the connections and it worked for about a week and now it's acting strange. Fully charged or down like it is now it acts the same. Did I get a bum meter? There should be a video in the link below.
