Service And Repairs 5; Fusible Link - Toro ProCore Processor Service Manual

Fusible Link

The ProCore Processor uses a fusible link for circuit
protection. This fusible link connects the main wire har-
ness to the starter B+ terminal and positive battery cable
(Fig. 13). If the link should fail, current to the machine will
cease. Refer to electrical schematic and wire harness
drawings in Chapter 9 -- Electrical Diagrams for addi-
tional fusible link information.
Testing
Make sure that ignition switch is OFF and disconnect the
negative battery cable from the battery terminal. Then
disconnect the 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 disconnected fusible link
connector and the link terminal at the starter motor (Fig.
14). If the fusible link is open (no continuity), replace the
fusible link harness.
After testing is complete, make sure that fusible link har-
ness connectors are securely attached to starter and
machine wire harness. Connect positive battery cable to
battery terminal first and then connect negative cable to
battery.
