Component Testing; Ignition Key Switch - Toro Reelmaster 4500–D 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: 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 func-
tions may be tested to determine whether all circuits are
being completed while the key is moved to each posi-
tion.

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.
