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 on the switch).
NOTE: See the Kubota Workshop Manual, Diesel En-
gine, SM--E3B Series for engine component testing in-
formation.
CAUTION
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Ignition Switch
The ignition (key) switch has three positions (OFF, ON
andSTART).Theignitionswitchislocatedonthedash
panel (Fig. 6).
Testing
The switch terminals are identified as shown in Figure
7. 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 betested to determinewhether
continuity exists between the various switch terminals
for each switch position. Disconnect wire harness con-
nector from key switch and verify continuity between
switch terminals in the different switch positions.
