1. 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.
2. 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.
3. 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.
4. 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.
