Having said that, this writer has also noticed that many technicians and mechanics across all ages and skill levels display a distinct resistance to using oscilloscopes in diagnostics because oscilloscopes are considered difficult to use, and their (displayed) results are almost impossible to decipher. This last point is relevant to this article in the sense that many “complex” diagnostic issues can be diagnosed relatively easily with an oscilloscope, and in particular, with a multi-channel digital storage oscilloscope that can record live date in “movie” format. More specifically, in small independent workshops that a) often cannot afford to keep scan tools updated, b), often cannot afford dealer-level scan tools, and/or subscriptions to access OEM service information, and c), often try to diagnose complex issues without adequate diagnostic equipment. The transition into this writer’s (almost) second career path as a mobile diagnostician since his semi-retirement happened by accident, and while we don’t have to go into the details of that happy accident here, what this writer can say is that most of his consultations happen in small independent workshops.
