PTO Enabled 1 Check the PTO switch. Deactivate PTO
P-brake not
activated.
2 Check P-brake Activate P-brake
Battery
voltage
3 Make sure the 20A wired fuse is intact. Replace fuse
4 Measure the battery voltage, >12.0V. Charge battery
5 Make sure the screw terminals are securely attached
to the battery terminals.
Tighten the screw
terminals on the battery
terminals.
6 Measure the voltage of the red cable to J1 (pin 8).
The voltage should be equal to the battery voltage.
Check the cable, go to
step 11 and step 12.
Starter relay 7 Check the orange cable and connectors between the
relay and the start motor.
Repair the cable or
replace the cabling
8 Make sure the relay clicks when the key is turned to
"Start".
Replace relay
P-brake
switch
9 Check the P-brake microswitch. Replace the
microswitch.
PTO button 10 Loosen connector J6 and measure the resistance
between the orange, gray and yellow pairs in the
cable connectors. When the PTO switch is pressed,
the orange cables should make contact but not the
others. When the PTO button is raised, the orange
cables should not make contact but the others
should.
Replace the PTO
button.
Wiring fault 11 Check the red cable and connectors from the relay
(connector 30) to J1 (pin 8).
Repair the cable or
replace the cabling.
12 Check the blue cable and connectors from the battery
to J1 (pin 7).
13 Check the white cable and connectors from J1 (pin 3)
on the control board to the relay (connector 85).
14 Check the brown cable and connectors from
J1 (pin 5) on the control board to the relay
(connector 86).
15 Check the gray cable and connectors from J7 (pin 1)
on the control board to the key switch (connector A).
16 Check the gray cable and connectors from J7 (pin 2)
on the control board to the key switch (connector A).
17 Check the orange cable and connectors from J6
(pin 4) on the control board to the PTO switch.
18 Check the orange cable and connectors from J6
(pin 1) on the control board to the PTO switch.
19 Check the brown cable and connectors from J3
(pin 2) on the control board to the connector before
the P-brake.
20 Check the blue cable and connectors from J3 (pin 3)
on the control board to the connector before the
P-brake.
21 Check the blue cable and connectors from the
connector before the P-brake to the P-brake
microswitch.
22 Check the yellow cable and connectors from
the connector before the P-brake to the P-brake
microswitch.
Key switch 23 Measure the voltage on the gray cable from J7
(pin 1) when the start key is turned to "Start". The
voltage in the cable should then be 12V.
Replace the key switch
Control card 24 Measure the voltage on J7 (pin 2) and J7 (pin 4). The
voltage should be equal to the battery voltage.
Replace the control
card
