Major electrical issue

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

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.

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

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.

He's gone.
