Fusible Links - Toro Groundsmaster 360 Service Manual

Fusible Links

The Groundsmaster 360 uses four (4) fusible links for
circuit protection. Two (2) of these fusible links are in-
cluded in a three (3) wire harness that connects the
starter B+ terminal to the wire harness (Fig. 55 and 56).
An additional fusible link is used that connects the start-
er B+ terminal to the alternator B+ terminal (Fig. 55 and
57). The remaining fusible link is included in the wire har-
ness and connects the starter G terminal to the engine
run solenoid pull coil. If any of these links should fail, cur-
rent to the protected circuit will cease. Refer to the elec-
trical schematic and wire harness drawings in Chapter
9 -- Foldout Drawings for additional circuit information.
NOTE: The fusible link harness shown in Figure 56
uses the fusible links in connector terminals A and B on
Groundsmaster 360 2WD machines. Groundsmaster
360 4WD machines use the fusible links in connector
terminals B and C. The third fusible link is not used on
the Groundsmaster 360.
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. Use a multimeter to
make sure that continuity exists between the fusible link
terminals. If a fusible link is open, replace the link.
After testing is complete, make sure that fusible link is
securely attached to engine component and wire har-
ness. Connect positive battery cable to battery terminal
first and then connect negative cable to battery.
