emmawatson Posted June 11, 2015 Report Share Posted June 11, 2015 Hi anyone had their electrical outlet tester have all 3 lights, (2 yellows and a red) light up at the same time? What kind of wiring configuration would cause that? Is it dangerous? Need electrician. Any help would be appreciated. Thanks!! Quote Link to comment Share on other sites More sharing options...
Marc Posted June 11, 2015 Report Share Posted June 11, 2015 If you're referring to those testers that sell for about $10 at big box stores- they're unreliable. Consult with a better tester like the Inspector III. Marc Quote Link to comment Share on other sites More sharing options...
mjr6550 Posted June 12, 2015 Report Share Posted June 12, 2015 Yes I have. And I have never figured out what it means, other than something is wrong with the wiring to that receptacle. Quote Link to comment Share on other sites More sharing options...
Scottpat Posted June 12, 2015 Report Share Posted June 12, 2015 Most likely the outlet has more than one problem and the little tester is doing all it can. Think of it as information overload.. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted June 12, 2015 Report Share Posted June 12, 2015 It means that there's a problem with the receptacle that the tester was not designed to detect. I've had it happen when a 120-volt receptacle was wired with 240-volts. I've also had it happen when the hot and neutral were reversed, the neutral connection was loose, and there was a load on the circuit downstream. Bottom line: When you see this, you need to pull out a regular multi-meter to figure out what's actually going on. Quote Link to comment Share on other sites More sharing options...
