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: See the Perkins 100 Series Workshop Manu-
al for more component testing information.

Ignition Switch

The ignition (key) switch has three positions (OFF, RUN,
and START). The terminals are marked as shown. The
circuitry of the ignition switch is shown in the chart. With
the use of a multimeter (ohms setting), the switch func-
tions may be tested to determine whether continuity ex-
ists between the various terminals for each position.
Verify continuity between switch terminals.
