Best I can tell, a wire loosened, connected with another wire and.....meltdown. I haven't been able to find a new transfer relay switch .

So, you're sure it's the xfer switch? Doesn't sound like you're all that sure about it.

Yes you can use your inverter for short periods provided it has a transffer switch of its own.. Now I can bypass a auto transfer switch.. but alas I do nto feel comfortable telling others how.

If the transfer switch is a 3-way (Short/Genny/Inverter) and no inverter sub panel I would avoid all 120 volt use.

In my case the line is like this (simplifed stuff left out)

Shore---ATS--_main breaker box--Branch (30 amp)--Inverter---Sub panel--Stuff

If yours is like that you can still run the "Stuff". But not for long cause it eats batteries.

Oh. I do have a way to plug in my converter independent of the RV that extends the "Stuff" run time to.. Forever

Assuming you have an inverter/charger, IMO don't use the inverter for 120v just yet. A straight inverter could be used from battery power, but not by using the shore power cord for "whole house" with that damage.

Perhaps with the inverter/charger (assuming it is not showing faults), you can disconnect its output 120v that goes to where the damage is, and connect a new 120v cord that has receptacles on it, so you can plug in an appliance or two to get by.

You will need to recharge the house batteries somehow.

I would avoid all 120 volt operations!
Depending on your ability, you could wire around a bad transfer switch.
