Fusible Link Harness - Toro GroundsmasterR 4300-D Service Manual

Fusible Link Harness

The Groundsmaster 4300--D uses four (4) fusible links
for circuit protection. Three (3) of these fusible links are
located in a harness that connects the starter B+ termi-
nal to the wire harness (Figs. 44 and 45). The remaining
fusible link is included in the wire harness and connects
the starter terminal to the engine run solenoid pull coil.
If any of these links should fail, current to the protected
circuit will cease. Refer to wire harness drawings in
Chapter 8 -- 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 dis-
connect positive (+) cable from battery (see Battery
Service in the Service and Repairs section of this chap-
ter). Locate and unplug fusible link connector from ma-
chine wire harness. Use a multimeter to make sure that
continuity exists between the fusible link terminal on the
starter B+ terminal (terminal J1 on fusible link harness)
and each of the terminals in the link harness connector
P1. If any of the fusible links are 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 testing is complete, make sure that fusible link is
securely attached to starter B+ terminal and machine
wire harness. Connect positive (+) battery cable to bat-
tery terminal first and then connect negative (--) cable to
battery.
