Power Take-Off: Testing and Inspection
Power Take-Off (PTO) Indicator Inoperative
POWER TAKE-OFF (PTO) INDICATOR INOPERATIVE
CIRCUIT DESCRIPTION
This symptom chart will aid in diagnosing a failed power take-off (PTO) indicator. This diagnostic assumes that the PTO solenoid is functional and only
the indicator is failing to come on. When the ignition switch is in RUN, voltage should be present on the Ignition 3 Voltage circuit. When the PTO
switch is turned to ON, the LED will illuminate. The indicator has its own ground circuit. The LED and PTO solenoid have different ground circuits.
Therefore, the LED may be illuminated when the PTO solenoid is disengaged.
