Component Testing
For accurate resistance and/or continuity checks, electrically
disconnect the component being tested from the
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,
V2403--M--T--E3B Series at the end of Chapter 3 -- Kubota
Diesel Engine.
CAUTION
When testing electrical components for continuity
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. 11). The terminals are
marked as shown in Figure 12. The circuit wiring of the
ignition switch is shown in the chart. 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 position. Verify continuity
between switch terminals.
