Good luck Mex
As for the OP problem
I don't believe this is a wiring defect
Wear? Maybe, age yes
This is a 12 yr old RV,
My uncle traded his Thor , but the problem seemed to be related to the ABS power circuits, IIRC the abs power relay gets its power from this sub fuse B
And is the only circuit using enough power to reach the limit of the fuse the other circuits would melt wiring before drawing over 50 amps and blowing that fuse
Not to mention blowing their own lesser fuse first
The ignition circuit do not carry that much power
They control relays that switch the power circuits
And there are a lot of RVs out there on this W22 chassis
I think
An on going wiring problem would have been noticed and brought to attention
Find the per fuse for the abs and remove it for testing purposes
