Like a light bulb .
Most electrical systems can be replaced .
Who, would scrap a house . Because the wiring & metre box took a ' lightning ' strike .
I have seen a flooded car , rebirthed, with second hand
( wreaker-yard ) electrical parts .
A 3 month old car, with seat-belts eaten by rats ,
rebirthed the same way .
Both would have been write-offs, by their insurance companies . But some people prefer what they have saved for .
Better the devil you know, than what you don't .

PS : those insurance companies source used parts from the same wreckers.
