Reverse Safety Switch
The Reverse Safety Switch is a simple metal tang
switch mounted on a bell crank of the drive pedal shaft.
When the reverse pedal is depressed, the bell crank will
rotate towards the rear of the tractor, pressing the reverse
switch into the hydro control rod. See Figure 7.8.
Seat Safety Switch
The Seat Safety Switch is mounted inside the seat. It
contains two sets of N.O. contacts See Figure 7.9.
• The yellow wire goes to the RMC module. When the
seat is vacant, the contacts close, providing a
ground path to the RMC module. If the seat is
empty, the circuit is completed, turning off the RMC
module.
• The yellow wire with white trace goes to the brake
switch. When the seat is vacant, the contacts close,
providing 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 pri-
mary windings of the magneto, turning off the
engine.
• The two green wires are ground wires.
• The most common problems are likely to be caused
by bad grounds in the green wires.
NOTE: The seat switch connector is a shorted N.C. connector. That means when the connector is unplugged,
a tiny jumper inside the connector shorts out all of the contacts. When the connector is shorted, the cir-
cuit thinks that the seat is empty.
