Performing Closed Current Draw Test

2013 Mini Cooper Countryman, Standard TransSECTION Performing Closed Current Draw Test
WARNING: This page does not describe the selected car, but rather 208 other vehicles, including the 2010 BMW Z4, 2010 BMW X6 M, 2010 BMW X6, 2010 BMW X5 M, and 2010 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
  • Select proper measuring device (DISplus, MoDic or DVOM)
    • Remember amperage draw in excess of 10A will damage DVOM.
    • Use inductive amp probe of DISplus when amperage draw is high.
      • When using DISplus inductive probe, clamp on negative battery cable with:
      • Arrow pointing away from battery. Switch off all consumers.
      • (It is not necessary to disconnect B- from body when using inductive probe).
  • Connect (-) test lead to negative battery terminal and (+) test lead to a known good ground.
  • Ensure all systems are OFF ! 
  • Be sure DVOM is on and set in proper mode. 
  • Disconnect battery ground lead from body.
  • Observe meter reading, wait for vehicle to enter sleep mode.
  • Identify faulty circuit by disconnecting fuses, relays, control modules or connectors, observing meter readings.
  • Defective circuit is found when current is below maximum closed current for vehicle being tested.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
