I bought an inexpensive (16) DVM at Wal Mart that I use for the motorhome 12v
testing. It seems to work ok, but the manual is a waste of time, and I am no pro at using its functions by any means.
On the subject of voltage at the campgrounds, I have had recent problems where I knew the voltage was not correct, as my TV/VCR would only work on tv tuning, and the VCR would not play. Then with the gen set running it was fine. We also popped the campground circuit breaker running a toaster oven and a/c, which I thought was a total of not more than 30 amps. draw
Related question- can we use 50 amp plug ins, simply by converting the plug end itself? Or do you have to have your electrical system set up differently? My plug ends are max 30 amp. type.
Lastly-I have seen the plug in type voltage readers for your a/c outlets...any one using these?
