One afternoon, I found myself chasing a flickering display on a JCB, and it hit me,
doing a quick continuity check on those suspect connectors saved me a ton of time.
Just probe, give it a wiggle, and keep an eye on the reading.
Often, the simplest tests can reveal the problem before you end up tearing half the cab apart

I remember a time when a loader just wouldn’t start, and the voltage was all over the place. My first move is always to check the ground paths, then I measure the key circuits for steady voltage. It’s a quick and methodical approach that usually leads me right to the issue without having to search blindly.

After getting zapped by some intermittent signals on a JCB, I figured out that using a multimeter to test the voltage drop across joints while the machine is running is a game changer. It helps me catch those sneaky wiring faults quickly, keeps me in the cab instead of crawling under panels, and saves me from hours of guesswork.
