Ohmmeter Connections
Procedure
Results
Main field (rotor)
Disconnect the P10 and P11
connectors and connect the
ohmmeter to P10-1 and P10-2
leads.
Place the ohmmeter on the
R x 1 scale.
If functional, see Section 1,
Specifications. Low
resistance, rotor windings
shorted. High resistance,
rotor windings open.
B1/B2 stator windings
Connect the ohmmeter to the
P11-1 and P11-2 leads.
Note
: Disconnect P11 and J11
to perform this test.
Place the ohmmeter on the
R x 1 scale.
If functional, see Section 1,
Specifications. Low
resistance, B1/B2 windings
shorted. High resistance,
B1/B2 windings open.
P1 ground connection
Connect the ohmmeter to the
P1-9 and ground.
Place the ohmmeter on the
R x 1 scale.
If functional, zero ohms
(continuity). Any other
reading indicates a poor
ground connection.
Low oil pressure (LOP)
safety shutdown switch
Connect the ohmmeter to the
P13-1 and engine block
(ground).
Place the ohmmeter on the
R x 1000 scale. This test is
not conclusive until the
temperature shutdown
switches are checked.
If functional, zero ohms
(continuity). Then, disconnect
LOP switch lead and isolate
terminal. Meter reading
should show an open circuit.
High exhaust
temperature (HET), low
coolant (LCS) safety
shutdown switches
Connect the ohmmeter to the
P1-15 and engine block
(ground).
Note
: Remove and
isolate the LOP switch lead.
Place the ohmmeter on the
R x 1000 scale.
If functional, open circuit. Any
continuity suggests an
inoperative temperature
switch(es). Disconnect
individual leads to inoperative
switch.

8.2 Remote Panels (Optional)
Kohler Co. offers three remote panels for connection to
the generator set.
D
A panel with a start/stop switch
D
A panel with a start/stop switch and two gauges
(engine oil pressure and water temperature)
D
A panel with a start/stop switch and four gauges
(DC
voltmeter,
engine
oil
pressure,
water
temperature, and hourmeter)
If difficulty with the remote operation occurs, test the
switch, gauges, and gauge senders using the following
procedures. See Sections 10.6, 10.7, or 10.8 to identify
the location for the appropriate panel.
Troubleshooting Remote Start Panels
Generally, if the sender changes its resistance values as
its respective pressure/temperature changes, it is
working correctly. An inoperative sender will either be
open or shorted. Refer to Figure 8-4 and Figure 8-5 for
resistance values.
