Thought those new wireless testers were just a gimmick...
A guy on a job in Springfield swore by his, so I borrowed it to check a door lock circuit on a 2004 Kone. It actually saved me about twenty minutes of pulling wire through a tight chase. Anyone else made the switch yet?
My old boss at the auto shop had me checking overhead bus bars with a basic probe. Took forever and felt so unsafe on a wobbly stool. I totally get what @maryr43 means about a time saver. Having the right tool that lets you just stand there and point? That's not just saving minutes, it's saving your back and your peace of mind. It changes the whole job from a chore to something you can actually do right.
Gotta wonder if it's really that big of a deal. A decent stool and a careful hand got the job done for years. Seems like a small comfort turned into a must-have.
