5. The Reverse Safety Switch is a simple metal
contact tang. When the drive pedal is pressed
into reverse, the reverse switch is pushed into a
bolt. This provides a path to ground.
See Figure 7.9.
6. The Seat Safety Switch consists of a pair of
simple metal contact tangs attached to the seat
mounting bracket. See Figure 7.10.
NOTE: The rubber mounts for the seat bracket
insulates it from ground. There is a ground wire
that provides a ground for the seat bracket. A
failure in that wire will prevent the seat switch
from working. See Figure 7.10.
• The yellow wire with white trace is connected to
the front spade terminal on the seat safety
switch. When the seat is vacant, the tab on the
seat bracket closes a ground path in series with
the PTO switch. If the PTO is ON and the seat is
empty, the circuit is completed, shorting out the
primary windings of the magneto, turning off the
engine.
• The yellow wire is connected to the rear spade
terminal on the seat safety switch. When the
seat is vacant, the tab on the seat bracket closes
a ground path in series with the brake switch. If
the brake is not applied, and the seat is empty,
the circuit is completed, shorting out the primary
windings of the magneto, turning off the engine.
• The most common problems are likely to be
caused by physical damage: a broken insulator
between the switch and the seat bracket, an
unplugged wire, or a bent tang.
7. The starter solenoid is mounted underneath
the battery. The mounting bracket is visible from
the left side of the engine. See Figure 7.11.
• When the proper safety conditions are met,
(brake applied, PTO OFF) the orange wire with
white trace energizes the windings that magne-
tize an iron core, pulling the contacts closed
between the two heavy posts, connecting bat-
tery power to the starter motor.
