Component Testing; Ignition Switch - Toro 30821 Service Manual

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 more component testing information, see
the Kubota Workshop Manual, Diesel Engine, 05 Se-
ries.

Ignition Switch

The ignition (key) switch has three positions (OFF, ON/
PREHEAT, and START). The terminals are marked as
shown. The circuitry of the ignition switch is shown in the
chart below. 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.
