Converters are one of the least understood electronics in the RV. Besides scoping the input ac voltage, you need to measure the battery charging current. If the converter is hardly charging, the ac waveform will look perfect. You really need a shunt or clamp on amp meter connected to the dc line.
The ac line mimics the dc line.
Also many WFCO converters have a history of not getting into boost mode. Check the dc voltage directly at the converter. If the voltage is below 14V then it's probably not in boost. No boost equals no big load on the ac.

I am in contact with an electronics guy in my home town. He is going to take a look at my WFCO converter and then we are going to scope it with AC, Champion 46515 open synchronous gen and then on to the Champion 2000i.
Now, I saw the pics that were posted showing the wave form of a Champion open synch gen powering a 1500 watt heater and the wave form powering the WFCO.
Now, I am looking for pics of the waveform with PDCO converter powered by the Champion 2000i. All this before spending more money.
