Identification should include
- measuring the draw, according to manufacturer guidelines, using an ammeter
- diagnosing the cause by isolating the excessively drawing circuit by disabling/disconnecting portions of the circuits or components (methodically from Maxi Fuses to Mini Fuses).

Process/Skill Questions:
- What is the typical allowable range for a parasitic draw?
- What is key-off load?
- How and why would a parasitic draw test be performed?
