Component Testing; Ignition Switch - Toro Greensmaster 3250-D 04383 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).
Note: See the Briggs and Stratton Vanguard/Dai-
hatsu Repair Manual for 3 Cylinder Water−Cooled
Diesel Engines for additional component testing in-
formation.

Ignition Switch

The ignition (key) switch has three positions (OFF, RUN,
and START). The terminals are marked as shown. The
circuitry of the ignition switch is shown in the chart. With
the use of a multimeter (ohms setting), the switch func-
tions may be tested to determine whether continuity ex-
ists between the various terminals for each position.
Verify continuity between switch terminals.
