See Figures 1 and 2
- Follow the coil wire from the center terminal on the distributor cap to the end at the ignition coil. Make sure the transaxle is in Park (AT) or Neutral (MT) and that the ignition is turned OFF .
- Separate the wiring harness connector from the ignition module at the distributor. Inspect for dirt, corrosion and damage. Reconnect the harness if no problems are found.
Push the connector tabs together to separate.
Attach a 12 volt DC test light between the coil Tach terminal and an engine ground, then crank the engine. If the light flashes or is continuous:
- Turn the ignition switch OFF .
- Disengage the ignition coil connector on top of the coil and inspect for dirt, corrosion and/or damage.
- Using an ohmmeter, measure the ignition coil primary resistance from the positive (+) to the negative (-) terminal of the ignition coil. See the corresponding figures for terminal locations.
- The ohmmeter reading should be 0.3-1.0 ohms. If the reading is less than 0.3 ohms or greater than 1.0 ohms, the ignition coil should be replaced.
- Using an ohmmeter, measure the coil secondary resistance; connect it to the negative (-) terminal and the high voltage terminal.
- The resistance should be 6,500-11,500 ohms with the ohmmeter set on ohms x 1000. If the reading is less than 6,500 ohms or greater than 11,500 ohms, replace the ignition coil.
