Yep, I have service manuals for the 20RZ. I have “them” actually — separate manual docs for the generator set and the controller. There is some info for the block heater install too. Surprisingly, there doesn’t seem to be a simple data sheet in the doc pack.

The genset manual is all the wiring diagrams for the generator end and controller. The engine manual has a placeholder saying you have to get it from ford.

I have an operation manual too.

I can email’em, PM me with your address.

You need to wire it as shown in the drawing I sent. The CTs are “current transformers” and they look like doughnuts. If you only see “one leg” going through the hole in the middle of the CT, then that’s your problem. Find the other wire as marked on the drawing and pass it through the middle too. Each wire has to be in-phase (check the labels on the wires and compare them to the drawing, and has to go the same direction through the CT. The drawing is pretty clear (note where the dot on the CT is too, the wires need to pass through the side shown with the dot), make your unit like the drawing and you should be good.
