(Classic® 300D Kubota)
The battery may be
discharged. Check, and if
necessary, charge or replace
the battery.
The battery cables or battery
connections may be loose or
corroded. Service the battery
terminals.
Make sure battery is fully
charged and properly
connected per the wiring
diagram. Turn on the
run/stop switch, and within 30
seconds, press the start
button while checking for
positive battery voltage where
the lead #62 connects to the
starter solenoid.
• If voltage is present when the
start button is pressed, check
that the engine block is
properly connected to the
negative battery terminal. If
the engine block is properly
connected, the
starter/solenoid is defective
and should be serviced or
replaced.
• If no voltage is present:
• Check the wiring connecting
the starter solenoid, ammeter,
start relay, and start button.
See wiring diagram.
• Check the start button.
• Check for battery voltage at
the start relay coil, between
leads #212C(+) and lead
#55(-) within 30 seconds of
turning on the run/stop switch
and while pressing the start
button.
• If voltage is present, replace
the start relay.
• If voltage is not present,
check the #55 lead, all the
conductors and devices
between the #212C lead and
the positive battery terminal.
