From the field
The same lessons come up again and again from people actually doing the job:
People think I just fix wiring. A modern car is a computer on wheels — I'm diagnosing sensors, ECUs, and networks, tracing faults through miles of wiring. It's detective work, and the cars only get more electronic.

Getting EV-qualified was the best decision I made. As cars go electric, the demand for high-voltage skills has exploded, and there just aren't enough of us. It's a genuine premium specialism with a huge future.
EV specialist · 6 years in
Everyone worried EVs would kill the trade. The opposite happened — electric cars need auto electricians more than ever, and the diagnostic side has never been more in demand. I've gone self-employed and I'm flat out.
