TROUBLESHOOTING:
7-WAY WITH INTERIOR LIGHTS
INTERIOR LIGHTS DO NOT COME ON
Step 1: Inspect the wiring and conrm that all connections are tight.
Step 2: Check for a voltage greater
than 10 volts to the lights, as
shown.
• If yes, inspect the wiring
between the nosebox and the
lights for defects.
• If no, continue to the next step.

Step 3: Check for a voltage greater
than 10 volts.
• If yes, inspect the wiring in the
nosebox for defects.
• If no, continue to the next step.
Step 4: Check for a voltage greater
than 10 volts.
• If yes, replace the cover
assembly.
• If no, inspect the wire between
the stud and the 7-way for
defects. If no defects are
noted, inspect the 7-way cable
between the tractor and the
nosebox for defects.
• If all voltages are good,
continue to the next step.
Step 5: Place the jumper between the
posts.
• If the lights come on, check the
wiring between the nosebox
and the external switch (if
installed) for defects.
– To check the operation of
the external switch, proceed
to the next step.
• If the lights do not come on,
replace the cover assembly.

Step 6: Position meter to measure
the resistance reading.
• Press for continuity, if meter
has this feature.
• Place leads as shown.
Press interior light switch - readings
should be 0 or very low resistance.
• No - Inspect wiring between
the nosebox and the switch
for defects, inspect switch for
defects and operation.

INTERIOR LIGHTS DO NOT COME ON
Step 1: Inspect the wiring and conrm that all connections are tight.
Step 4: Check for voltage greater
than 10 volts.
• If yes, replace the cover
assembly.
• If no, inspect the wire between
the stud and the dual pole for
defects. If no defects are noted,
inspect dual pole cable between
the tractor and the nosebox for
defects.
• If all voltages are good:
– If exterior switch is used
skip to step 6.
– If no exterior switch is used
proceed to step 5.
Step 2: Check for a voltage greater
than 10 volts to the lights, as
shown.
• If yes, inspect the wiring
between the nosebox and the
lights for defects.
• If no, continue to the next step.
Step 3: Check for a voltage greater
than 10 volts.
• If yes, inspect the wiring in the
nosebox for defects.
• If no, continue to the next step.

Step 5: Place the jumper between the
posts.
• If the lights come on and there
is no external switch, replace
the cover assembly.
• If there is an exterior switch,
proceed to the next step.
Step 6: Position the meter to read
resistance.
• Press for continuity, if the
meter has this feature.
• Place leads as shown.
• Press the interior light switch.
• Voltage should read 0 or a very
low resistance.
• If no, inspect the wiring
between the nosebox and the
switch for defects.

TROUBLESHOOTING:
DUAL POLE WITH INTERIOR LIGHTS
INTERIOR LIGHTS DO NOT COME ON
Step1: Inspect the wiring and conrm that all connections are tight.
Step 2: Turn the interior lights on by pressing the switch on the nosebox, then
continue to the following steps.
Step 3: Check for a voltage greater
than 10 volts to the lights, as
shown.
• If yes, inspect the wiring
between the nosebox and the
lights for defects.
• If no, continue to the next step.

Step 5: Check for voltage greater
than 10 volts.
• If yes, replace the cover
assembly.
• If no, inspect the wire between
the stud and the dual pole
positive for defects. If no
defects are noted, inspect the
dual pole socket, the cable
between the dual pole and the
tractor, and the nosebox for
defects.
• If all voltages are good,
continue to the next step.
Step 6: Place the jumper between the
posts.
If the lights come on:
• Check the wiring between
the nosebox and the external
switch (if installed) for defects.
• To check operation of the
external switch, proceed to the
next section.
• If the lights do not come on,
replace the cover assembly.
Step 4: Check for a voltage greater
than 10 volts.
• If yes, inspect the wiring in the
nosebox for defects.
• If no, continue to the next step.
