It's All Relative

In part 1 of a multi-part series on mechanical engine testing using a scope, we discuss relative compression. This is one of my FAVORITE tests to analyze the mechanical health of an engine quickly & non-intrusively. We discuss the the testing methods & variables that you may encounter. The next episodes in this series will cover pulse sensors & In-cylinder pressure testing. Facebook group-https://www.facebook.com/groups/223994012068320/?ref=bookmarksWebsite-https://autodiagpodcast.com/
