Testing Notes

CHECKOUT

^ 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.

EQUIPMENT
^ DIS adapter (Rotunda 007-00044)
^ Engine analyzer (Rotunda 002-00373)

NOTE:
^ The engine analyzer is used to diagnose problems in the secondary side of the ignition system.
^ If this section 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 (Ford Part# 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 clearance. The spark tester firing voltage should be approximately 28 Kv.
