Starter solenoid
The starter solenoid is mounted to the rear frame cross
member, under the seat. See Figure 7.10.
• When the proper safety conditions are met (brake
applied, PTO OFF), the orange wire with white
trace energizes the windings that magnetize an
iron core, pulling the contacts closed between the
two heavy posts, connecting battery power to the
starter motor.
PTO Relay
The PTO relay is mounted on the rear frame cross mem-
ber, under the seat. See Figure 7.10.
The PTO relay disengages the PTO clutch when it is
energized and latches on until the PTO switch is turned-off.
The list below details the function of the PTO relay.
