Component Testing
For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplug the ignition switch connector before
doing a continuity check on the switch).
NOTE: For engine component testing information, see
the Kubota Workshop Manual, Diesel Engine, 05 Se-
ries.
CAUTION
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Ignition Switch
The ignition (key) switch has three positions: OFF, ON/
PREHEAT and START (Fig. 5). The switch terminals are
identified as shown in Figure 6.
The Standard Control Module (SCM) monitors the op-
eration of the ignition switch. When the ignition switch is
in the ON position, the SCM power input LED should be
illuminated.
Testing
1. Before disconnecting the ignition switch for testing,
theswitchanditscircuitwiringshouldbetestedasa
SCM input (see Standard Control Module in this sec-
tion).
2. If the SCM verifies that the ignition switch and circuit
wiring are functioning correctly, no further switch testing
is necessary.
3. If the SCM determines that the ignition switch and cir-
cuit wiring are not functioning correctly, test ignition
switch as follows:
A. Make sure ignition switch is in the OFF position.
Disconnect wire harness connector from ignition
switch.
B. The circuitry of the ignition switch is shown in the
chart in the right column. With the use of a multimeter
(ohms setting), the switch functions may be tested to
determine whether continuity exists between the
various terminals for each switch position. Verify
continuity between switch terminals.
C. Replace ignition switch if necessary.
D. If the ignition switch tests correctly and a circuit
problem still exists, check wire harness (see Electri-
cal Schematics and Circuit Drawings in Chapter 8 -
Foldout Diagrams).
E. Connect machine wire harness connector to igni-
tion switch.
