ONECONNECT DIAGNOSTIC GUIDE
INTERIOR LIGHTS DO NOT COME ON
Step 1: Inspect the wiring and confirm that all connections are tight.
Step 4: Check for voltage greater

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
