...When hooked up to external power or to the internal generator of my Vogue Class A, I get 13 to 14 volts through my converter (at the battery) depending on battery charge (8D). When hooked up to my Champion 3500 generator (early model) I never get more than 12.3 volts no matter what the battery charge. Needless to say, this is killing my battery. Is this a sine wave problem (dirty or square) or could it be related to the outlet plug issue discussed here so well?...
I had a similar problem with an old Magnetek converter. I suspected it was low voltage that was causing the problem but, in fact, it must have been related to either the waveform or the line frequency.
After I replaced the Magnetek with a solid-state converter, I experimented with the Magnetek and a variac. I could lower the input voltage to 90v and the DC output remained fairly constant (in fact it raised just slightly). However, when running from my generator, at over 110v, the output dropped to less than 12.6v. I measured all the voltages (AC and DC) with a Fluke RMS meter.
The Magnetek is a ferroresonant design. I believe it was either reacting to the fundamental line frequency being a little low, or to the waveform distortions (other frequencies and harmonics) riding on the AC waveform.
