Title: Identify parasitic (key-off) battery drain problems.
Course: Diesel Equipment Technology I (20107-I) > Section: Electrical/Electronic Systems: General Electrical Systems

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 would a parasitic draw test be performed? Why is this test conducted?
