Tales from the Dyno - the case of the NASTY Tune.

well hose me. I went outside to mow the lawn and discovered that I had a flat tire. Instead of reaching for the airchuck right off the bat I thought I would diagnose it a little further. Busted out my trusty ol scope (no multimeters here), had a little challenge figuring out where I needed to place the probes, so I settled on the tread and the rim. Proceeded to observe the output while I added air to the tire.

So, I got this notice on the screen that said "no signal". Does that mean I need to install some kind of TPMS so the scope can tell me where the leak is? or should I have attached the other probe to the tread as well, just on the other side of the tire?

I think you should have poked the test leads into the tire that still had air in it to get a baseline reading.

Should have waved your wheel and tire cert at it, would have inflated itself without fixing the leak.

So I guess a pocket full of cash trumps giving good advice, or even being the least bit humble regarding skills that most highschoolers used to get as part of a standard curriculum.

And closed...at the request of the OP...
