Component Testing

For accurate resistance and/or continuity checks, elec-

tricallydisconnect thecomponentbeing testedfrom the

circuit (e.g. unplug the ignition switch connector before

doing a continuity check).

NOTE: For engine component testing information,see

the Kubota Workshop Manual, Diesel Engine,

V2403--M--T--E3B Series at the end of Chapter 3 -- Ku-

bota Diesel Engine.

CAUTION

Whentesting electrical componentsfor 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/

PREHEAT and START (Fig. 11). The terminals are

marked as shown in Figure 12. 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

thevariousterminals for eachposition. Verify continuity

between switch terminals.
