Checked all other outlets at this point with a plug in night light. No power. Pulled GFI out and it is not getting any input power in inverter mode. Works like it's supposed to with shore power. Any suggestions would be most welcome as I've now gone from thinking I could just replace the inverter to discovering that easy fix ain't the issue.
you have an inverter circuit breaker problem
you have 120v pass thru on shore power,
did you try it with the generator running
but no power to other outlets on inverter, that used to work on inverter
you have something that must be reset or replaced, and it IS in the inverter
