Preliminary Test Notes

^ Visually inspect the engine compartment to ensure all vacuum hoses and spark plug wires are properly routed and securely connected.

^ Examine all wiring harnesses and connectors for insulation damage, burned, overheated, loose or broken conditions.

^ Be certain the battery is fully charged.

^ All accessories should be off during diagnosis.


Required Equipment

NOTE: Obtain the following or equivalent test equipment.

^ EI (Low Data Rate) Adapter (Rotunda 007-00044).

^ Engine Analyzer (Rotunda 002-00373).


NOTE: If this portion of the diagnostic procedure is to provide accurate results, it is essential that the calibration of your engine analyzer be maintained. Refer to your equipment manual. If this is not available, an estimate of the calibration can be made by connecting the spark tester (Special Service Tool D81P-6666-A or equivalent) to a properly operating ignition system and measuring the firing voltage of the spark tester only. Do not include the firing voltage of the rotor-to-cap gap. The spark tester firing voltage should be approximately 28 KV.
