Test NTC-15: Checking Secondary Ignition & Timing

NOTE: Possible causes are: secondary ignition system (water test), ignition coil defective or secondary ignition system defective.
  1. Turn ignition off. Connect an engine analyzer to engine. Start engine. Allow engine to idle. If engine will not idle, maintain a constant RPM above idle. Following equipment manufacturers instructions, observe secondary ignition pattern. If pattern is okay, go to next step. If pattern is not okay, repair secondary ignition system as necessary. Perform TEST VER-2A: ROAD TEST FOR NON-OBD II  .
  2. Using a spray bottle, spray ignition cables with water and observe ignition pattern. DO NOT spray inductive pickup. If ignition pattern did not change, go to next step. If ignition pattern changed, repair indicated secondary ignition component. Perform TEST VER-2A: ROAD TEST FOR NON-OBD II  .
  3. Momentarily remove and install secondary ignition cables one at a time and observe secondary ignition KV pattern. If open circuit secondary voltage is at least 25 KV, test is complete. If open circuit secondary voltage is not at least 25 KV, replace ignition coil. Perform TEST VER-2A: ROAD TEST FOR NON-OBD II  .
