Ignition System
Whenever troubleshooting an electrical problem you should first check all terminal connections to be sure they
are clean and tight. Also be sure that colors match when wires are connected. Use the following pages as a guide
for troubleshooting. The resistance values are also given on the specification pages.
Condition: No Spark or intermittent spark
Replace Spark Plug
•
Disconnect the black wire at the COl module
to isolate the ignition from the kill system.
Does it have spark?
No
+
Disconnect the exciter coil and pulse coil connec-
tor from the COl module. Measure the resistance
of the exciter coil and pulse coil (where applica-
ble). Refer to the chart on page 10.3 or the wiring
schematic for meter connections and specifica-
tions. Compare results to the specifications on
the chart. Are all within specifications?
Yes
+
Yes---...
-Test the ignition switch, engine stop
switch, and speed limiter circuit for
shorts to ground.
-Check terminal board or connectors
for moisture, wire color matching or
corrosion.
No ---..
Inspect connectors, wiring and
grounds to the component in
question. Replace the compo-
nent if a wiring problem cannot
be found.
Check coil ground connection between engine and coil
mount using an ohmmeter. The coil mount should
have good continuity to ground on the engine (0-.2 Q).
No--"" Clean coil mounting area.
Repair ground wire connections.
Yes
Disconnect and check the secondary coil. Resis-
tance values should be:
Primary Side - Primary Wire Tab to Ground
(on coil mount or engine): .3 to .5 Ohms
Secondary Side High Tension Wire to engine
ground- Cap installed - 11 ,300Q
Cap removed - 6300Q
Are these values within specs?
Yes
No
-.j
Replace the ignition coil.
If all of the above tests are within specifications, and all grounds, connections, and wire color coding
have been inspected, perform voltage output tests on following page or replace the COl module.
