Component Testing

For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplug the ignition switch connector before
checking continuity on the switch terminals).
NOTE: For engine component testing information, see
the Yanmar Model 4TNV86CT−DTR Service Manual or
Troubleshooting Manual, or the Kubota Model
03−M−DI−E3B Workshop Manual.

Fusible Link Harness

Your Groundsmaster uses two (2) fusible links for circuit
protection. These fusible links are located in a harness
that connects the starter B+ terminal to the wire harness
(Fig. 28). If either of these links should fail, current to the
protected circuits will cease. Refer to wire harness
drawings in Chapter 9 − Foldout Drawings for additional
fusible link information.
Testing
1. Park machine on a level surface, lower cutting units,
engage parking brake and stop engine. Remove key
from ignition switch.
2. Disconnect negative battery cable from battery ter-
minal and then disconnect positive cable from battery
(see Battery Service in the Service and Repairs section
of this chapter).
3. Locate and unplug fusible link connector from ma-
chine wire harness.
4. Use a multimeter to make sure that continuity exists
between the fusible link terminals.
5. If either fusible link is open, replace the fusible link
harness.
NOTE: It is not recommended to replace individual fus-
ible link conductors of the fusible link harness. If any of
the harness links are open (failed), replace the entire
fusible link harness.
6. After fusible link testing is complete, make sure that
fusible link harness is securely attached to starter B+
terminal and wire harness. Connect positive battery
cable to battery terminal first and then connect negative
cable to battery.

When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
