Fusible Link
A Workman HDX Auto vehicle uses three (3) fusible links
for circuit protection. These fusible links are located in a
harness that connects the engine starter motor B+ termi-
nal to the vehicle rear wire harness (Fig. 29). If any of
these links should fail, current to the protected circuit will
cease. Refer to electrical schematics and wire harness
drawings in Chapter 9 − Electrical Drawings for addition-
al fusible link information.
Testing
1. Park machine on a level surface, raise bed, stop en-
gine, apply parking brake and remove key from ignition
switch.
2. Install bed support on bed lift cylinder to prevent bed
from lowering.
3. Disconnect negative battery cable from battery ter-
minal and then disconnect positive cable from battery
(see Battery Service in the Service and Repairs section
of this chapter).
4. Locate and unplug fusible link connector P1 from ve-
hicle wire harness.
5. Use a multimeter to make sure that continuity (zero
ohms) exists between each terminal pin in connector P1
and connector J1 at the starter (Fig. 30). If any of the fus-
ible links are open (infinite ohms), replace the fusible link
harness.
6. After testing is complete, make sure that fusible link
harness connectors are securely attached to starter and
vehicle wire harness.
7. Connect positive battery cable to battery terminal
first and then connect negative cable to battery.
8. Remove bed support from cargo bed lift cylinder and
lower bed.
