POWERLINK SYSTEM
Some V-Twin engines are equipped with the Power-
LinkSystem, an on-board generator system for
riding tractors that provides 120 volt, 60 cycle AC to
a GFCI receptacle provided by the OEM.
The PowerLink system will not function unless the
parking brake on the tractor is ENGAGED (1), Fig.
52, and the PTO on the tractor is OFF. The Power-
Link system will shut down if there is a system or
temperature overload, or if there is a ground fault.
4. If the power goes OFF the GFCI is working
correctly. Press the reset button to restore power.
NOTE: Use only OEM approved GFCI
components.
Resetting PowerLink System
NOTE: Turn OFF or unplug any device or appliance
that was connected to the PowerLink
System. Verify that the reset button on the
GFCI has not been tripped.
1. The engine must be running with the parking
brake set and the PTO DISENGAGED.
2. Actuate the PowerLink reset switch. Move the
reset switch to the OFF position, then return it to
the ON position. For operator safety there is a
two second delay in power to the GFCI
receptacle after reset.
Testing the GFCI
Fig. 33
1. The engine must be running with the parking
brake (1) set and the PTO DISENGAGED.
2. Plug in a trouble light or radio to confirm that
electrical power is present.
3. Press the GFCI test button (1) to trip the GFCI,
Fig. 34.
If the device is still being powered the GFCI is NOT
working correctly. Replace the GFCI.

Test PowerLink System
If a problem occurs and the PowerLink system is
suspect, follow the test procedure in exactly the
order shown to isolate the faulty component.
Required tools:
• Digital Multimeter, Tool #19464
• PowerLinkTest Box, Tool #19528
1. Test the GFCI (previous procedure).
2. Test the parking brake interlock switch.
3. Test the PowerLink reset (ON-OFF) switch on
the tractor.
4. Check alternator output.
Test PowerLink System Ground Continuity
Digital Multimeter #19464 is used to test the ground
circuits.
With the meter in the +))))) (DIODE TEST) position,
and the test leads attached to the grounds, a
CONTINUOUS TONE indicates CONTINUITY
(complete circuit). NO TONE indicates NO
CONTINUITY (open circuit). Open circuits are
displayed as OL.
1. Insert RED test lead into V receptacle in meter.
2. Insert BLACK test lead into COM receptacle.
3. Test for continuity between the inverter case and
the engine frame, Fig. 35.
