17.28.The Reverse Safety Switch is a simple metal
contact tang. The gear selector touches it when
placed in the reverse position, providing a
ground path through the gear selector lever
itself. See Figure 17.28.
• The red wire with black trace leads directly back
to the RMC module.
• When the RMC module is turned-on, the rest of
the system effectively does not “see” the reverse
safety switch.
• This wire can be identified at the RMC module
connection, and tested for continuity to ground in
REVERSE position.
• The most common problems are likely to be
caused by physical damage: a broken insulator
between the switch and the fender, an
unplugged wire, or a bent tang.

17.29.The Seat Safety Switch consists of a pair of
simple metal contact tangs attached to the seat
mounting bracket. See Figure 17.29.
• 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 with black trace 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, short-
ing-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.
