Ignition System: Service Precautions

Connecting A Tachometer To DLC 1:






PRECAUTION

1. Do not leave the ignition switch on for more than 10 minutes if the engine does not start.

2. With a tachometer connected to the system, connect the tester probe of the tachometer to terminal IGG of the data link connector 1.

3. As some tachometers are not compatible with this ignition system, we recommend that you confirm the compatibility of your unit before use.

4. Never allow the tachometer terminals to touch ground as it could result in damage to the igniter and/or ignition coil.

5. Do not disconnect the battery while the engine is running.

6. Check that the igniter is properly grounded to the body.
