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
The battery must be installed with negative terminal attached to black ground wire. Negative terminal is
incorrectly 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 fluid is low, fill to just below split rings with water. Charge with 6 amp
charger until fully charged.

exposed the bare wire. Replace the wire or repair with electrician's tape if the wire strands have not
been damaged.

against a moving part.
