Here is ScannerDanner working on a 2001 ISC8.3 CAPS fuel system for long crank time. He goes down the rabbit hole a little thinking it's a possible fuel issue but gets back on track.
I thought it was pretty neat as I don't see a lot of HD scope work over here in the states. Maybe help somebody out? Quite a long video, but waveform capture is around 21:30.
It's a little old for the stuff I work on, but may come in handy, and you never know.
Great to see ScannerDanner getting involved with HD and I've no doubt it will help.
For scope work in the states, worth checking out Diesel Laptops for scope work as they have a branded 4425A PicoScope as well as training. We are hoping to get more content for HD and OH available soon, as well as some dedicated guided tests. I am looking to expand on these tests so if there's anything you think might be of use please let me know!
Thanks again for sharing on the forum!
