Well, after two short ones, we’re back to a longish piece, but one that’s really worthwhile. In it, Robert from New York walks the reader through his diagnostic process in sorting out an excessive parasitic drain on a 2014 Cadillac CTS that resulted in a dead battery / no start situation after 2-3 days of non-use.

He details the steps (and the thinking that drove those steps) as he worked through this tricky diagnostic assignment, providing the results of each step. Essentially, he ties the entire process together from start to finish, which is immensely helpful for the reader trying to follow along. It is a great writeup and one that earned many kudos from the Diagnostic Network membership.

We definitely think it is worth your time.
