Component Testing
For accurate resistance and/or continuity checks, elec-
tricallydisconnectthe componentbeingtestedfrom the
circuit (e.g. unplug the ignition switch connector before
doing a continuity check on the ignition switch).
NOTE: For engine component testing information, see
theKohlerEngineServiceManualattheendofChapter
3 -- Kohler Gasoline Engine.
CAUTION
Whentesting electrical componentsfor continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Ignition Switch
