Ignition Coil Secondary Signal Check
WARNING: This page does not describe the selected car, but rather 34 other vehicles, including the 2001 BMW Z8, 2001 BMW Z3, 2001 BMW X5, 2001 BMW M5, and 2001 BMW M3. However, it is still accessible from the selected car via links, so may be relevant.
- Connect engine analyzer and Adapter (127020) as described in IGNITION COIL PRIMARY SIGNAL CHECK . Remove ignition coil. Connect a spark plug wire (between coil and spark plug) to cylinder being tested. Connect inductive pickup Blue lead, on lead to cylinder being tested. See Fig 1.IGNITION COIL RESISTANCE - Ohms @ 68°F (20°C)
Primary Secondary .8 (1) Not Measurable (1) Specification is approximate. - Produce stopped signal on oscilloscope by pressing "R" button on tester. Display of ignition signal on oscilloscope will be strongest when inductive clip and Black lead are connected to same cylinder. Display on oscilloscope may be disturbed by neighboring ignition leads (this is normal).
