Electrical System
Fusible Link (Serial Number Below 310000000)
ProForce Debris Blowers with a serial number below
310000000 use a fusible link for circuit protection. This
fusible link connects the main wire harness to the starter
B+ terminal and positive battery cable (Fig. 12). If the
link should fail, current to the machine will cease. Refer
to electrical schematic and wire harness drawings in
Chapter 7 -- Electrical Diagrams for additional fusible
link information.
Testing
1. Make sure that ignition switch is OFF.
2. To prevent unexpected machine operation, discon-
nect the negative battery cable from the battery terminal
(see Battery Service in the Service and Repairs section
of this chapter). Position disconnected negative cable
away from the negative battery terminal.
3. Locate and unplug fusible link connector from ma-
chine wire harness.
4. Use a multimeter to make sure that continuity exists
between the disconnected fusible link connector and the
link terminal at the starter motor (Fig. 13). If the fusible
link is open (no continuity), replace the fusible link har-
ness.
5. After testing is complete, make sure that fusible link
connectors are securely attached to starter and ma-
chine wire harness.
6. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from 10
to 15 ft--lb (14 to 20 N--m). Make sure that battery cover
is secured.
