295: 2017 Buick Lacrosse Parasitic Draw

Per request, I'm sharing a case study this week on the show. A 2017 Buick Lacrosse that sometimes will die overnight, but other times does not. We brought this one to our shop to set up for intermittent parasitic draw testing. I'll share my process 7 approach for this type of issue along with some pitfalls to avoid with modern GM wiring schematics.
