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
Make sure that ignition switch is OFF. Disconnect nega-
tive battery cable from battery terminal and then discon-
nect positive cable from battery (see Battery Service in
the Service and Repairs section of this chapter). Locate
and unplug fusible link connector from machine wire
harness. Use a multimeter to make sure that continuity
exists between the fusible link terminals. 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.
After fusible link testing is complete, make sure that fus-
ible link harness is securely attached to starter B+ termi-
nal and wire harness. Connect positive battery cable to
battery terminal first and then connect negative cable to
battery.
