Hi,
It is hard to tell from this picture, but the black soot indicates an electrical overload event or an electrical dead short occurred, leaving a trail of soot from burnt wire insulation.
It also looks like there may be a bare copper wire with the insulation burnt off. We need closer pictures to confirm this and the wire coming from the wall. Please post some closer pictures so we can confirm this. Also, burnt electrical wire often leaves a unique smell. I am not sure you are trained in that smell, but it smells like burnt plastic or rubber.
Is this on your 2004 T1950 you talked about in some of your previous posts?
If it is, a Romex 120 VAC cable runs in a covered compartment (pipe and wire chase) behind the toilet, feeding the water heater's electric element.
See these pics. I am referring to the cable from a 2004 T1950 being restored. The water heater is removed, but you can see the white Romex cable.
Here is the cable that runs behind the toilet but is covered with a wood panel cover; it was not exposed to the toilet area when it was made originally. The cable goes under the shower basin, then across the back wall, again all covered in wood panels, and stops at the water heater.
If you are showing a burnt-up Romex cable, the bigger question is how it became exposed in the open next to the toilet flush pedal?
Did someone, a prior owner etc, re-route that cable?
Here is what Sunline installed originally. A view looking down from above.
You can see the boxed-in pipe and electrical wire chase behind the toilet. No wires were exposed; only the toilet fresh water fill hose and the bowl sprayer were.
With the toilet removed, only the water fill hose is exposed.
If you are showing a Romex cable burnt up, let us know. I can point you to more damage in other places.
I hope this helps.
John
