Component Testing; Ignition Switch - Toro Multi Pro 5800 Service Manual

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 connector be-
fore doing a continuity check on the ignition switch).
NOTE: See the Kubota Workshop Manual (05--E3B
Series) for engine component testing information.

Ignition Switch

The dash mounted ignition (key) switch has three (3)
positions (OFF, ON/PREHEAT and START).
Testing
1. Make sure ignition switch is off. Disconnect wire har-
ness electrical connector from the ignition switch.
2. 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. The ignition switch terminals are
marked as shown in Figure 5. The circuitry of this switch
is shown in the chart below. Verify continuity between
switch terminals.

3. Replace ignition switch if necessary.
4. If switch tests correctly and circuit problem still ex-
ists, check wire harness (see Electrical Schematic and
Circuit Drawings in Chapter 8 -- Foldout Drawings).
5. When testing is complete, connect wire harness
electrical connector to the ignition switch.
