Most techs rely on digital tools, but I fixed a transponder glitch with a simple multimeter check. It was a small win that reminded me of the basics.
I mean, back in the day, we traced faults with just a meter and a paper schematic. Now, if the display freezes, you're stuck without a clue, idk maybe it's just me but that's a real worry.
Seeing the data flow in real time is oddly satisfying.
