Component Testing
For accurate resistance and/or continuity checks, elec-
tricallydisconnectthe component beingtestedfromthe
circuit (e.g. unplug the ignition switch connector before
doing a continuity check).
NOTE: For engine component testing information, see
the Kubota Workshop Manual, Diesel Engine, 03--M--
E3BSeriesattheendofChapter 3 -- KubotaDieselEn-
gine.
CAUTION
Whentesting 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 on the console arm has three
(3) positions (OFF, ON/PREHEAT and START) (Fig.
15).
Testing
1. Before disconnecting the ignition switch for testing,
the s witch and its circuit wiring should be tested as a
TEC--5002 input with the Diagnostic Display (see Diag-
nostic Display in the Troubleshooting section of this
chapter). If the Diagnostic Display verifies that the igni-
tionswitchandcircuitwiringarefunctioningcorrectly,no
further switch testing is necessary. If, however, the Dis-
playdeterminesthattheignitionswitchandcircuitwiring
are not functioning correctly, proceed with test.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Disassemble console arm to gain access to ignition
switch (see Console Arm Disassembly in the Service
and Repairs section of Chapter 7 -- Chassis).
4. Disconnect wire harness electrical connector from
the ignition switch.
5. The ignitionswitchterminals areidentifiedas shown
in Figure 16. The circuit logic of the ignition switch is
shown in the chart below. With the use of a multimeter
(ohmssetting),theswitchfunctionscanbetestedtode-
termine whether continuity exists between the various
terminals for each switch position. Verify continuity be-
tween switch terminals. Replace switch if testing identi-
fies that switch is faulty.

6. If ignition switch tests correctly and circuit problem
stillexists,check wireharness(see ElectricalSchemat-
icsandWireHarnessDrawingsinChapter10 -- Foldout
Drawings).
7. After testing is completed, connect the wire harness
connector to the ignition switch.
