11. This places the pickup with the ground plane facing or nearest to the coil With the ground plane facing the coil weaker unwanted signals are not strong enough to make it past the ground plane The secondary signal is typically strong enough to use the pickup in this manner 2 Move the pickup around the coil and see where the signal is the strongest and looks the best You may need to increase the scope trigger level depending on the signal strength for best viewing As you move the pickup around the coil you may see the shape of the pattern change This is likely due to the location of the secondary and primary windings inside of the coil The pattern tends to portray the windings closest to the pickup signal level is not strong enough try Side A facing the coil This places the signal plane closest to the coil giving the strongest signal NOTE On some coils the pattern looks like a conventional secondary pattern On others there may be much less detail NOTE On some coils you will note a large difference in the pattern depending on the exact location of the pickup in relation to the coil Pick the spot that gives the best pattern and allows the pickup to stay put otherwise improvise to hold the pickup in the desired place NOTE Each pickup should be located in the same position on each coil so the signal is the same from each one 3 4 3 Connecting to Ignition Systems Always proceed in the following order
12. Examine both the spark voltage and burn time duration Many coils have diodes in the secondary circuit and the secondary resistance of these coils can not be measured Refer to manufacturer specifications for information about these coils Coil oscillations on coil on plug systems may be lower than coil oscillations of previous conventional systems In some cases normal oscillations may be as low as zero Compare each vehicle coil with others on the vehicle to identify a coil with a different characteristic e Check the spark line on all cylinders Suspect any that are smooth less turbulent or with a different slope Sparks that occur outside the combustion chamber are typically more stable than sparks that occur in the combustion chamber 4 2 Troubleshooting This section addresses common problems with triggering and unstable patterns that may occur when testing with the DIS Adapter For problems at any engine speed including cranking e Check all lead connections Check for correct positioning of all pickups Pickups must contact each coil identically for consistent test results Generic pickups are directional with sides marked A and B Turn over the pickup to change the sensitivity Check all tester ground connections 17 Operation Troubleshooting NOTE Because spark duration and voltage are related any system problem that affects one affects the other as well e If spark voltage i
