deluco Report post Posted June 25, 2013 My 50 amp plug has two blue led's on the top. Both usually light up when plugged into 50 amp shore power. Sunday I plugged in and only one of the led's lit up...the one on the left top. The one on the right lit very briefly as I plugged it in, then it went out. All systems worked fine, even running both a/c units at the same time...and the TV and entertainment system. The last time I noticed that the right-side led was out, it was as a result of a shore power problem at a Florida camp site, after a power outage. After the power outage when the power came back on, the wall plugs in my RV stopped working. They moved me to a new site and that solved the problem and both led's were lit. This time no such problem...just the right LED not lit. A friend speculated that it's just a grounding problem at the site, since all systems worked. Any thoughts on this? Should I be concerned?

wolfe10 Report post Posted June 25, 2013 Jim, Our speculation won't help you-- could be a faulty LED or an indication of a real problem. You need to VERIFY that your shore power is correct. If you are safe working around 120 VAC, use your voltmeter to check the CG outlet: If not, have the CG do it. The two outer straights are the hots L1 and L2. The center straight is the neutral. The center round is ground. So: From either outer to center straight or center round= 120 VAC Center round to center straight= 0 VAC Outer straight to outer straight= 240 VAC Brett Share this post Link to post Share on other sites
deluco Report post Posted June 26, 2013 Thank's Brett. There was a tech onsite and he said the receptacle read fine with his meter and all systems worked fine in the RV. I go to this campground a lot, so next time I'll pay attention to the plugs and follow up. Thank's again. Share this post Link to post Share on other sites
