Fusible Link Harness
The Groundsmaster 4300--D uses four (4) fusible links
for circuit protection. Three (3) ofthese fusible links are
located in a harness that connects the starter B+ termi-
naltothewireharness(Figs.44and45).Theremaining
fusiblelink isincluded inthe wireharness andconnects
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
Makesurethatignitionswitchis OFF.Disconnectnega-
tive(--) batterycable frombattery terminaland thendis-
connect positive (+) cable from battery (see Battery
Servicein theServiceand Repairssection ofthischap-
ter). Locate and unplug fusible link connector from ma-
chine wire harness.Use a multimeter tomake sure that

NOTE: Itisnotrecommended toreplace individualfus-
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
