I was being sarcastic.
Clearly there’s no fuse in the fusebox, and if there is, it should have been backed up with a fusible link in the affected harness itself of a much lower rating to guard against the problem.
It’s idiot engineering. In my circle we discuss this at my prodding. It’s a pet theory of mine that when engineers retire, so does the bulk of their experience, resulting in such problems.
It is NOT isolated to any one industry.
Yes. Over-engineered crap is still crap. I watch a mechanic "South Main Auto Repair" on YouTube. He's a wizard when it comes to tracking wiring and code problems. Fuses working but circuit isn't or is throwing codes. He's in up-state NY, and in the rust belt. Had one truck in that was simply stumping other shops. Turned out to be the chassis ground strap had rotted. It was braided copper and crumbled in his hand as he went to check it. The truck was maybe three years old. Some things would work then not, then all kinds of unrelated codes were thrown. What a fricking nightmare.
