Operation CHARM: Car repair manuals for everyone.

Preliminary Checkout and Notes

NOTES:
^ This procedure begins with a complaint that the engine stops at unexpected times but can be restarted. In situations like this there are two things that are very important. The technician must obtain as much information directly from the customer about the conditions under which the problem occurs, and the service history of the vehicle must be thoroughly reviewed to avoid repeat replacement of good components.

^ Two testers are available for assistance with intermittent diagnosis. The Rotunda TFI/EEC-IV Intermittent Analyzer (Part# 007-00035) is available for diagnosing intermittent problems and provides a quick connection to the TFI-IV ignition system and records intermittent failures. The TFI-IV intermittent analyzer can not be used with TFI modules with Computer Controlled Dwell (CCD) unless a CCD update is added to the analyzer. The Rotunda Ignition System Tester (Part# 007-00008) provides a quick means of separating primary ignition system problems from fuel, carburetion, EGR, or other system problems causing similar symptoms. It can be used on most ignition systems. It will detect any primary ignition system problem, but it is particularly useful in detection of intermittent problems.

INSPECT
^ 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.
