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. The
circuit wiring of the ignition switch is shown in the chart.
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 terminals.

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, the Module
start output LED should also be illuminated.
