SECTION 13: TROUBLE SHOOTING GUIDE
If the above steps fail to correct the problem, take the unit to your local authorized service dealer for repair.
Trouble
Possible
Cause(s)
Corrective Action
Engine will
not crank
Safety switch
button not
depressed.
Battery installed
incorrectly.
Battery is dead
or weak.
Blown fuse or
circuit breaker.
Engine ground
wire loose.
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.
The battery must be installed with negative terminal attached 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. All batteries are to be fully charged before installing. Refer to “Quick Start”
battery guide that came with the operator’s manual.
Check fluid level in battery. If fluid is low, fill to just below split rings with water. Charge
with 6 AMP charger until fully charged.
Refer to operator’s manual for fuse box location. Replace fuse with automotive type
fuse. Fuses seldom fail without a reason. The problem must be corrected. 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 should have a black ground wire running from engine to frame or mounting
bolt.
