The "test" breaker in the breaker box trips, even though we replaced the GFI upstairs.
If the schematic that deandec posted matches your rig as well, that GFCI outlet is powered by the inverter and should work regardless of the status of the transfer switch...at least until your batteries go flat! However the rest of the inverter outlets (TV, reefer, etc.) are fed through that GFCI outlet so it could be confusing. If there is no AC power your inverter will automatically start (as long as it is turned on) and feed the other outlets. There should be two 20 amp breakers for the inverted output that are remote and probably near the inverter.
You problem is not rocket science but deductive diagnostics that involve inverters and AC and DC, something that most electricians cannot handle. Your expert needs to ignore a little AC coming from your inverter and focus on the main shore power problem.
Remember, most electricians think a 30 amp rv plug goes in a dryer outlet!!!!
