If INSITE™ is available, monitor the remote PTO switch for proper operation. If
not, follow the troubleshooting procedures in this section.
Locate the remote PTO ON/OFF switch. Tag and remove the two connectors from the terminals on the switch. Touch the multimeter probes to the terminals on the switch.
Remove one of the multimeter probes from one of the switch terminals and touch it to the chassis ground. The switch
must be ON. Measure the resistance. The multimeter
must show an open circuit (100k ohms or more). If the circuit is
not open, the switch has failed. Refer to the OEM troubleshooting and repair manual for the replacement procedures.
If the remote PTO switch passed all of the previous checks, pin 15 and pin 10
must be checked for an open circuit, a short circuit to ground, a short circuit from pin to pin, and a short circuit to an external voltage source. Connect the switch to the wiring harness.
Connect all components after the repair is complete.
