Component Testing

For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. disconnect the ignition switch connectors
before doing a continuity check on the ignition switch).
NOTE: See the Kubota 05 Series Diesel Engine Ser-
vice Manual for more component testing information.

Ignition Switch

The ignition (key) switch has three positions (OFF, ON,
and START). The terminals are marked as shown. 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.
