No shore power or solar power on Etrek

[Broken Bird]

New to us 2015 Etrek RSEM won't accept shore power. The shore power light illuminates momentarily and that's it. The inverter showes no power coming in.
Additionally, the solar controller is blank. Everything with a Roadtrek sticker say to use factory settings. Has anyone had experience with this?

I have experience with the shore power side and first indication to me is an Automatic Transfer Switch issue, especially if the air conditioner or electric wtr. heater won't power on. If neither of those large consumption items are working on shore power the issue isn't with the inverter, they're strictly receiving power directly from the pedestal, but is likely in the transfer switch. Otherwise if they are working, it's likely your salesman switch is off, the inverter has a tripped breaker or faulty fuse or the batteries are so low the inverter isn't seeing them. If you can start the engine crank up the generator and it may shock the system on.
