In this part 3 video we will be reinforcing what we've learned so far on a live car. As well as determining if we can view coil trigger signals with a test light. Then finally we switch to a 2016 GMC with a misfire that just had a new coil installed, without a fix. #picoscope #rosedaletech #scannerdannerpremium

On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better online training of how to troubleshoot automotive electrical and electronics systems anywhere!
