TROUBLESHOOTING ENGINE
Engine Dies when Steering Handles
are Engaged
1.
Check if parking brake is set.
• Release parking brake.
NOTE:
When parking brake is on, system is
designed to kill the engine if either steering handle
is engaged.
■
This circuit has a positive voltage with the key
on. Jumping the seat switch with exposed wires
could short out the main fuse or timer delay.
2.
Check seat switch and deck safety switch/jumper.
a.
Raise seat assembly and secure.
b.
Turn key switch “ON”, engage seat switch and
move deck to highest cut height position if
equipped with power tilt deck.
c.
Check voltage between the green timer delay
wire and red wire at the seat switch connector
on the main wire harness side. (See FZ25D
Wiring Diagram.) Both wires are located under-
neath the seat pan on the right side next to
steering pivot block.
• If there is voltage at one wire but not the other,
either the switches/jumper are defective or not
fully engaged. The red and green wires are
part of a series circuit that includes the seat
switch and deck safety switch (power tilt deck)
or weatherpack jumper.
• If there is voltage on only one wire check each
switch individually to determine which switch
is defective or not closed. The weatherpack
jumper should be connected to the main wire
harness, underneath the seat pan by the left
hand steering pivot linkage if there is not a
deck or a standard deck is attached.
• If using the power tilt option and you need to
check the deck safety switch refer to Figure
12 and troubleshooting deck safety switch. If
the deck switch is open the engine will kill
when pulling handles in.
3.
Check park brake switch.
• If there is voltage at both red/green wires men-
tioned in previous paragraph, check voltage at
yellow/red parking brake wires with the park
brake off.
• If voltage is not present, check the yellow/red
wire between the seat relay and parking brake;
and the pink seat relay/timer delay wire to deter-
mine which wire or relay is defective.
• If voltage is present at one yellow/red wire but not
the other, the parking brake switch is defective
and must be replaced.
