You may need to use a True RMS reading DVM to see the correct voltage (should be ~ 120 VAC) as the inverter is likely not supplying a true sine wave but a square wave or (likely) a stepped (“modified”) square wave approximation to a sine wave. A cheaper non RMS DVM will not be accurate for non-sinusoidal waveforms.2021 F350 with plug on dash. It only produces about 95 volts. Every other truck I have checked is putting out about 105 volts. My dealer tells me my truck is ”normal”. I think they can’t find the problem? Anyone have an opinion?
This sounds very logical. However, I used the same volt meter to check all the different vehicles. Mine said 95v and the other vehicles said 105 volts. ??You may need to use a True RMS reading DVM to see the correct voltage (should be ~ 120 VAC) as the inverter is likely not supplying a true sine wave but a square wave or (likely) a stepped (“modified”) square wave approximation to a sine wave.
