Looking for suggestions on what is causing this.
I always get a 50A reading on my load center, doesn't make any difference weather I am hooked up to 30A , 50A or Gen. It doesn't seem to affect anything in the coach.
I have looked for any fuses in transfer box, have made sure everything is tight, don't see any burnt wires. I have tripped and reset all breakers, including the breaker on Gen.

The display is reporting only what it's being told. The real "smarts" are on a board that is usually installed inside your AC breaker panel. Kill all your power sources, pop off the AC breaker panel and look for the EMS management board. There are some cable connections you can check, a fuse or two, etc. I'd give you more specific info but my EMS is 4 years older than yours and things might have changed.

You can also GENTLY remove the bezel and unscrew the display panel, ease it away from the wall and check the cable connection coming into it from the EMS module in the breaker box. Sometimes they vibrate loose (like mine did once) and give false display readings.

We had that issue with our 2006 Journey. The circuit board inside the power management box is bad and needs to be replaced. There was an issue where some of the resistors were not a high enough wattage rating and heated up to the point they "fell" of the board from the heat.

On mine, I tell it what amperage to expect by pushing the select button to match the amperage that I'm hooked to. The new fancy ones maybe a different.

Whoops, I don't have 50 amp, please ignore

Is the power management box a little circuit board that is behind the bezel ?
