This is a great example of just how tricky it can be to resolve an intermittent electrical system issue. Robert from New York submitted this great case study, which illustrates many of the concepts we have seen emphasized by the experts since we started this blog: having a clear diagnostic game plan, following each problem back to its source and not forgetting about checking for good grounds/ruling out potential shorts. What’s really great about this story is it concerns a vintage car (1969 Nova), proving that these concepts are critical whether the vehicle is an electronically advanced late model or a fairly basic 1960s muscle car.
