Hot/Neutral reversed

[Scooterfan]

Upon your advice I purchased an outlet tester for the 110v outlets in the MH. Cool (inexpensive) little tool! Checked all the outlets and they ALL had the same reading...
Hot/Neutral Reversed. OK, first off I'm a rookie when it comes to things electrical, so be kind ? But since ALL checked out the same (and ALL work OK it seems), where is the hot/neutral wires reversed? I'm plugged in at home (with an extension cord) to a 110v outlet (I have a 50 amp coach). Can you guide me ? Thanks in advance !

I assume you have checked the house outlet.

Like Kevin said. Start at house out let and then check extension cord. then on to MH.

You guys are awesome...did exactly that! AND, I discovered I had a mis-wired plug at the barn. When we did a little remodel that plug was re-wired. Hmmm...I must have done it backwards ? Those testers are really neat little tools. Thanks for all the advice. It all checks out OK now. Blessings
