That's something that we've consistently recommended to folks here. The little plug-in testers with three lights on them are inexpensive and will quickly tell you if there a wiring problem with your source. You'd still need a voltmeter to verify what the voltage is at any given moment. That way, you're much more in the driver's seat concerning what power you hook up to at any given location.
I've whipped out my three light tester and immediately verified that a power post in a CG was miswired. The CG owner started to argue with me until I told him that he could either walk down to the campsite and see for himself or he could accept my word that there was problem. Either way, I wasn't parking my trailer there and using his power post.
Paddler's recommendation regarding verifying the tightness of all connections in the convertor is a good one. We've had plenty of reports of loose connections in the trailer's power distribution panel (which is part of the convertor installation) from owners of new trailers as well. Disconnect from the CG's power post and wait an hour or more to let the capacitors in the converter discharge themselves. Then drop the panels and have at it. I'll bet you find at least one loose one in there. If there is a loose connection, be alert for wires that have slipped out from where they belong.
Here's a pic of the inside of a typical RV power panel:
Here's a pic showing both the power distribution section and the convertor below it:
The AC is on the left in the area where the circuit breakers and the 12vdc is on the right with all the colored fuses in a vertical row. AC is easily disabled by unplugging the shore line. Disabling the DC requires that you disconnect the batteries in some way. In your case, disregard the 12vdc for now and concentrate on the AC because that is likely where your problem is located. Check all the connections on the buss bars and on the circuit breakers. If anything seems loose, tighten it up.
