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?
