Trouble at Freedom Shores in Isla Aguada

A little bit elaborate and technical but I bought two of these (see below) and made up a plug and outlet device for our 50amp service which I can quickly plug into any receptacle using adapters to see what might be coming out. If you only have 30amp you only need one - or you can rig up and plug one into each/either side of your system if you have 50amp. This device will tell you if you are getting correct polarity and what voltage you are getting. There are other ways to do this a little cheaper but this is the quickest I have found. Of course you can do this with a regular voltmeter or rig up a simple plug to a meter - and then get a polarity tester. Anyway, they do not show the price online but as I recall I may have paid about $20? They also sell regular analog meters and polarity testers. I have purchased directly from them but some RV parts places do have these. If interested contact them.
