Engine/Generator Components - Kohler 10CCOZ61 Service Manual

With the generator set battery connected, the wiring
harness and some engine/generator components can
be checked with a voltmeter as described in Figure 7-8.
Place the controller or remote start/stop switch in the

NOTE: Voltage can only
be measured momentarily
since unit will not
continue to run after start
switch is released.

Voltmeter
Connections
prescribed position and check for 12 volts DC at each
component using a DC voltmeter. This will verify that the
switches function and 12 volt DC is present at each
component.
Remarks
Voltmeter setting 12 volts.
Disconnect hourmeter
leads and apply 12 volts
DC to hourmeter.
NOTE: Hourmeter is
polarity sensitive.
Voltmeter setting 20
volts AC or greater.
Start generator set by
holding Start/Stop switch in
Start and allow to reach
proper speed. Take reading
and then stop generator.
Voltmeter setting 12 volts
or greater. If lead can not
be disconnected, cut leads
and crimp-on fully insulated
push-on terminals.
Push out leads #6 and " P"
at the 4-pin connector.
Apply 12 Volts
DC to #6 lead and
momentarily apply 12
Volts DC to " P"lead.
Volts DC to " P"lead.
NOTE: Apply voltage
only momentarily to
" P"lead to prevent fuel
solenoid damage. This
coil draws 50 Amps. and
is intended only to energize
the solenoid.
Results
If wiring harness is good--12
Volts DC or greater. To
determine if hourmeter is good,
proceed to next step.
If good--hourmeter will
operate.
Reading of 12--15 Volts
indicates B1/B2 winding
is good.
If wiring is good--12 Volts DC.
To determine if fuel solenoid is
good, proceed to next step.
If good--fuel solenoid will ener-
gize and move plunger when
voltage is applied to " P"lead
and remain held in after " P"
lead is disconnected as long
as #6 lead has voltage applied
to it.
