CHARGING SYSTEM
NO SPARK, WEAK OR INTERMITTENT
SPARK
â—Ž No12 volt power or ground to CDI
â—Ž Spark plug gap incorrect
â—Ž Fouled spark plug
â—Ž Faulty spark plug cap or poor connection to high tension
lead
â—Ž Related wiring loose, disconnected, shorted, or corroded
â—Ž Engine Stop switch or ignition switch faulty
â—Ž Poor ignition coil ground (e.g. Coil mount loose or
corroded)
â—Ž Faulty stator (measure resistance of all ignition related
windings)
â—Ž Incorrect wiring (inspect color coding in connectors etc)
â—Ž Faulty ignition coil winding (measure
and secondary)
â—Ž Worn magneto (RH) end Crankshaft bearings
â—Ž Sheared flywheel key
â—Ž Flywheel loose or damaged
â—Ž Excessive crankshaft run out on magneto (RH) end -
should not exceed .005〃
â—Ž Faulty CDI module
MAIN FUSE ASSEMBLY
The main fuse assembly is located under the seat and has a
15-amp capacity.
NOTE: Use only the recommended fuse capacity, as
use of a higher amperage fuse to correct blown—fuse
situations could lead to electrical component
damage.
VOLTAGE REGULATOR / RECTIFIER
1. The voltage regulator / rectifier is located under the
headlight of right hand front cab.
2. If a problem exists with the charging system, test the
components around the regulator/rectifier to isolate the
component. If the stator is supplying sufficient AC current and
there is no DC current leaving the regulator/rectifier, replace
the component.
