Ignition System Performance Testing
Ignition Performance Testing is divided into two sections. The first
section consists of a flow chart. This chart presents the correct
sequence of performing ignition system performance tests to
effectively and efficiently check for problems in starting and running
the engine. Follow the steps in the order listed until the problem is
resolved and the ignition system meets specifications while the
engine is running.
The chart references specific performance tests that must be
completed to resolve each problem. These tests are described in
detail in the section which follows the flow chart.
The performance tests, identified as Test 1 through Test 7, contain
specific instructions for testing and servicing various ignition
system components. Use this section to perform the tests correctly
in accordance with the factory recommendations.
NOTE
After you complete each performance test refer back
to the flow chart for the next step. You must follow
the flow chart until the ignition system meets
specifications while the engine is running. The only
way to be sure that you have uncovered and repaired
all ignition system problems is to follow these
procedures in a systematic fashion.
If you only have problems in stopping the engine,
proceed directly to Test 2 - Stop Circuit Test.
