My 2019 Ranger is equipped with the 110V 150W receptacle on the rear of the center console. The receptacle only produces 52 volts. Ford dealership says this is how it's supposed to work. Can anyone with a similarly equipped truck and a TRMS meter confirm this is or is not how the device functions?

The only things I have plugged into the device are laptop chargers and a wireless router. ~50W.

Thanks in advance.

 

Are you measuring 52 volts 'hot' to 'ground'? If so, check 'hot' to 'neutral'. Many inverters actually have two 'hots', so 52 volts on each 'hot' will produce 104 volts between them.

 

Just checked again.

L-N: 50.0VAC
L-G: 7.5VAC
N-G: 11.5VAC

 

Try a small drill or some other 120v motor. Electronic devices usually drop the incoming voltage to whatever voltage they actually operate on.

 

Sorry I wasn't clear. The readings I provided are with no load connected. I'm measuring the voltage directly at the plug either with probes inserted into the receptacle or with a plug tester which exposes the hot and neutral for easier readings.

Unless the device is load sensing in some way? I'll give it a shot with a resistive load in an hour or two.

 

That may be the issue.... it's needing a load to produce 'full' voltage.
