Troubleshooting
Action
The start motor does not
start when the key
switch is turned to
START.
Cutting deck
lowered.
1
Make sure that the lift lever is in the
top position.
Parking brake
not applied.
2
Do a check of parking brake.
Apply parking brake.
Low battery
voltage.
3
Make sure that the 15A fuse is not
damaged.
Replace the fuse.
4
Measure the battery voltage, >12.0V. Charge the battery.
5
Measure the voltage of the red cable
connected to the ignition switch. The
voltage must be equal to the battery
voltage.
Repair the cable or re-
place the wiring.
Starter relay
malfunction.
6
Do a check of of the thin brown cable
between ignition switch and the start-
er relay.
Repair the cable or re-
place the wiring.
7
Do a check of the black cable be-
tween the starter relay and the nega-
tive terminal on the battery (-).
Repair the cable or re-
place the wiring.
8
Measure the voltage of the thin brown
cable to the starter relay. When the
key switch is turned to START, there
must be the same voltage in the ca-
ble as in the battery.
Replace the ignition
switch.
9
Measure the resistance of the relay. It
must be 3.7-4.2 Ω.
Replace the starter re-
lay.
Parking brake
microswitch
malfunction.
10
Do a check of the parking brake mi-
croswitch.
Replace the micro-
switch.
Lift lever mi-
croswitch mal-
function.
11
Do a check that the microswitch
changes the position when the lift lev-
er is lifted.
Replace the micro-
switch.
Wiring fault.
12
Measure the resistance between the
thin black cable to the starter relay
and the negative battery terminal. If
the parking brake is applied and lift
the lever in the top position, the re-
sistance must be low.
Go to next step.
13
Measure the resistance between the
black cable to the starter relay and
the connector to the wiring to the ped-
al plate 1 pin. The resistance must be
low.
Repair the cable or re-
place the wiring.
14
Measure the resistance between the
wiring to the pedal plate pin 5 and the
negative battery terminal. The resist-
ance must be low.
Repair the cable or re-
place the wiring.
