Component Testing; Ignition Switch - Toro Sand Pro 5040 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
checking continuity between switch terminals).

Ignition Switch

The ignition (key) switch has three positions (OFF, RUN,
and START) (Fig. 6). The switch terminals are identified
as shown in Figure 7.
Testing
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
switch position.
Unplug wire harness connector from switch and verify
continuity between switch terminals. Reconnect the har-
ness connector to the switch after testing.
