The goal at SD Premium is to make available an ever growing library of video resources that showcase diagnostic techniques taught both in my book and in my Engine Performance class at Rosedale Technical College. SD Premium contains coordinated playlists that match the chapters in my book as well as exclusive case studies, available only to Premium members. (*book not required) If you’re new to the field or have been a tech for a while and want to gain foundational knowledge of electrical and electronic systems diagnostics and troubleshooting, this is the place for you! The concepts taught here apply not only to all automotive systems, but also extend to HVAC, diesel, marine, motorcycle repair and many other industries.
