Repeat readings for each ignition coil:
9. If secondary winding for any ignition coil is not within the
acceptable range, replace the ignition coil. See Ignition System
Repair Procedures - Ignition Coil. After repairs are made, return to
Ignition System Performance Testing Flow Chart.
10. Reconnect all wires disconnected during test.
11. Return to flow chart.
Test 7 - Output Tests - Engine Running
CAUTION
The following tests must be performed with correct
test propeller and with the engine in a test tank.
Note that some performance problems cannot be
duplicated in a test tank, in these cases the tests
must be conducted with the engine mounted on a
boat and operated in open water.
NOTE
Make sure all electrical terminals are connected
during this test except those that are noted in the
test procedure.
Check for continuity between chassis ground and
the ground connection for the magneto plate, CD
Unit, and ignition coils before conducting the
following procedure.
These series of tests are designed to efficiently find faulty ignition
components that can cause an engine to run poorly. Use the flow
chart to systematically eliminate the possible causes to the
problems.
The tests assume that:
• The engine starts.
• Tune-Up Procedure has been performed, see Section 2.
• Ignition Timing and the Carburetor Synchronization Procedure
has been performed, see Section 2.
• Engine is at operating temperature.
• Tests are performed with engine running in forward gear.
• Tachometer is installed.
