The tool truck came around this week with this little gem in the latest flyer...

A “parasitic draw test switch”. For the low low price of $71 FUCKING DOLLARS (save $23!!). Come on, guys, you show this stuff to techs! We all know this is a $10 battery cutoff switch at any auto parts store. How does this even reach print? Not to mention the fact that it’s completely unnecessary!! If used, it adds a step to a very simple process, and necessitates disconnecting the battery to install, which you generally try to avoid unless absolutely necessary, especially during electrical diagnostics. This is beyond stupid, but I’m sure some slick tool guy who has never wrenched will sell them to rookies. Bugs the shit out of me.
