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 CDI module
to isolate the ignition from the kill system.
Does it have spark?
No
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 Ω).
Yes
Disconnect and check the secondary coil. Resis-
tance values should be:
Primary Side - Primary Wire Tab to Ground
(on coil mount or engine): .2 to .3 Ohms
Secondary Side High Tension Wire to engine
ground- Cap installed - 8000-9300Ω
Cap removed - 3000-4200Ω
Are these values within specs?
Yes
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 CDI module.
-Test the ignition switch and engine
stop switch circuit for shorts to
ground.
Yes
-Check connectors for moisture,
wire color matching or corrosion.
Clean coil mounting area.
No
Repair ground wire connections.
