Component Testing; Ignition Switch - Toro Groundsmaster 3280-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 be performed through voltage drop tests
without disconnecting the component.

Ignition Switch

The ignition (key) switch has three positions (OFF, ON,
and START). The terminals are marked as shown in Fig-
ure 5. The circuit wiring 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 position. Verify continuity between switch termi-
nals.

The Standard Control Module monitors the operation of
the ignition switch. If the ignition switch is in the ON posi-
tion, the Module Power input LED should be illuminated.
If the ignition switch is in the START position, both the
Module Power input and Start input LEDs should be illu-
minated.

When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
