Component Identification And Testing; Ignition Key Switch - Toro Reelmaster 6500–D Service Manual

Component Identification and Testing

For all electrical problems, use of the Quick Refer-
ence Troubleshooting guide is recommended. Us-
ing the Diagnostic ACE Display allows you to
quickly find the source of the electrical problem.
This section will define given components, and the tests
that can be performed on those components, when
those parts are disconnected from the electrical system.
For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplug the clutch switch connector before
doing a continuity check).
NOTE: Electrical troubleshooting of any 12 Volt power
connection can also be performed through voltage drop
tests without disconnection of the component.

Ignition Key Switch

The ignition (key) switch has three positions (OFF,
START and RUN). The terminals are marked as shown.
The circuitry of the ignition switch is shown in the chart.
With the use of a continuity tester, the switch functions
may be tested to determine whether all circuits are being
completed while the key is moved to each position.

When testing electrical components for conti-
nuity with a volt–ohm meter or continuity tes-
ter, make sure that power to the circuit has
been disconnected.
