Product Details:

How to diagnose parasitic battery drain correctly the first time is covered by AVI instructor Dave Hobbs in this video (LBT-270 Parasitic Current Draw with Dave Hobbs). In a step-by-step presentation, Hobbs covers the entire diagnostic process from how to identify customer complaints to verifying the final repair. Essential to the process is Hobbs description of the applications and functions of various meters and switches. To make a diagnosis as precise as possible, he teaches how to convert amps, volts and ohms into smaller values.

Rounding out the content of the video, Hobbs explores electricity flow; diagnostic roadblocks; comparing DTCs to drain characteristics, shorts, opens and high resistance circuits; and battery drain diagnostic preparation.
