Hello everyone! My name is Mark.
I've been a heavy duty truck tech for over 30 years, have seen the trucking industry from before the introduction of computer controls (and even before windshield wipers were electric if you can believe that!), the electronic invasion (as I call it), and through the years to its current state.
I've been fortunate to work for employers who value employee training and have done their best, but have never had "Dealer/OEM" level training.
But experience is the best teacher, and I am thrilled with the initial results I've had with my Picoscope,  performing a relative compression test to find a blown head gasket on a Series 60 Detroit, and then on a Prevost Bus find an intermittent engine flutter caused by a shorting TRS sensor harness.
This thing is AMAZING! I've had it two weeks and found the problem the dealer diagnosed as an injector harness failure...

SO anyway, Happy to be here, hope to learn from and contribute to the community library with waveforms.

Welcome to the house of Nerd-dom.

Surfing the site and reading the archives is "a real nice way to spend a day in Dayton, Ohio on a lazy Sunday afternoon..."


Sorry, couldn't resist
