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 Section 10, Voltage Reconnection and
Wiring Diagrams.
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 8-3 and Figure 8-4 for
resistance values. Refer to Figure 8-5 for
troubleshooting information on the remote start panels.

Component Ohmmeter Connections Procedure Results
Remote
start/stop
switch
Remote switch: yellow/red wire
terminal and black wire terminal.
Place the ohmmeter on the R x 1
scale. Press the rocker switch to the
START position.
Continuity, the switch is
functional. Open, replace switch.
Remote switch: grey/black wire
terminal and black wire terminal.
Place the ohmmeter on the R x 1
scale. Press the rocker switch to the
STOP position.
Continuity, the switch is
functional.
Generator set
ON light,
gauge lights,
DC voltmeter,
and hourmeter
Connect the red test lead to P3-4
and black test lead to P3-1.
Place the controller rocker switch to
the START position. Stop the
generator set when the test is
complete. Generator set does not
need to be running, just cranking for
this test. Note: If the hourmeter is
not illuminated, test it by connecting
it to a 12-volt battery. Note:The
hourmeter is polarity sensitive.
If 12-volts DC is present and the
component does not function
after the J3 is connected to the
controller P3, replace the
component(s).
Water
temperature
gauge
Connect the red test lead to P3-4
(socket side) and black test lead
to P3-2 (socket side).
Start the generator set for the test. If 0.5--12-volts DC is present and
the gauge does not function after
the J3 is connected to controller,
replace the gauge.
Oil pressure
gauge
Connect the red test lead to P3-4
(socket side) and black test lead
to P3-3 (socket side).
Start the generator set for the test. If 0.5--12-volts DC is present and
the gauge does not function after
the J3 is connected to the
controller, replace the gauge.
Note: Check continuity of gauge wiring and extension harness before replacing components.
