TROUBLE SHOOTING GUIDE
PROBLEM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Engine will not
crank.
Safety switch button not de-
pressed
There are two switches in the starting circuit of your unit:
the clutch pedal switch and the deck lift lever switch. Make
certain the actuator is fully depressing the buttons on each
switch.
Battery installed incorrectly The battery must be installed with negative terminal at-
tached to black ground wire. Negative terminal is identified
at the post by “NEG”, “N” or “ – “. The positive terminal,
identified by “POS”, “P” or “+”, must be attached to the
big red wire which goes to the solenoid.
Battery is dead or weak Check fluid level in battery. If it is low, fill to just below split
rings with water. Charge with 6 AMP charger until fully
charged.
Brown fuse or circuit breaker Replace fuse with 7-1/2 amp. automotive type fuse. Fuses
seldom fail without a reason. The problem must be cor-
rected. Check for loose connections in the fuse holder.
Replace fuse holder if necessary. A dead short may be in
the cranking or charging circuit where the insulation may
have rubbed through and exposed the bare wire. Replace
the wire or repair with electrician’s tape if the wire strands
have not been damaged.
Note: Look for a wire pinched between body panels,
burned by the exhaust pipe or muffler or rubbed against a
moving part.
Engine ground wire loose Engine should have a black ground wire running from en-
gine to frame or mounting bolt.

and choke for starting.
No spark to spark plug Spark plug lead disconnected. Connect lead. Hold spark
plug lead away from engine block about 1/8”. Crank en-
gine. There should be a spark. If not, have engine repaired
at authorized engine service dealer.
Faulty spark plug. To test, remove spark plug. Attach spark
plug lead to spark plug. Ground the spark plug body
against the engine block. Crank the engine. The spark plug
should fire at the electrode. Replace if it does not.

the better quality of cut.
