Fusible Links
Machines with diesel engines use four (4) fusible links
for circuit protection. Three (3) of these fusible links are
located in a harness that connects the starter B+ termi-
nal to the wire harness (Fig. 47). The remaining fusible
link is included in the wire harness and connects the
starter terminal G to the engine fuel stop solenoid pull
coil (Fig. 47). Machines with gasoline engines use a
fusible link integrated into the machine front wire har-
ness. The link connects the starter terminal B+ terminal
to the contacts of the main power relay. If any of these
links should fail, current to the protected circuit will
cease. Refer to wire harness drawings in Chapter 11 −
Foldout Drawings for additional fusible link information.
Testing
1. Make sure that ignition switch is OFF.
2. Disconnect negative (−) battery cable from battery
terminal and then disconnect positive (+) cable from bat-
tery (see Battery Service in the Service and Repairs sec-
tion of this chapter).
3. For Multi Pro 5800−D fusible link harness (Fig. 48):
A. Locate and unplug fusible link connector from
machine wire harness.
B. Use a multimeter to make sure that continuity ex-
ists between the fusible link terminal on the starter
B+ terminal (terminal J1 on fusible link harness) and
each of the terminals in the link harness connector
P1 (Fig. 48). If any of the fusible links are open, re-
place the fusible link harness.
4. For fusible link in wire harness (Fig. 47):
A. Locate and unplug machine wire harness con-
nector from the starter.
B. Use a multimeter to make sure that continuity ex-
ists across the segment of the wire harness with the
fusible link. For Multi Pro 5800−D machines, test be-
tween the wire harness connector at the starter and
the engine fuel stop solenoid connector for the sole-
noid pull coil (white wire). For Multi Pro 5800−G ma-
chines, test between the wire harness connector at
the starter and terminal 30 of the main power relay
connector (red wire).
C. If this fusible link should fail, make sure that the
wire harness is repaired with the correct fusible link.
Do not replace a failed harness fusible link with a
section of wire.

5. When testing is completed, make sure to connect all
disconnected wire harness components. Connect posi-
tive (+) battery cable and then negative (−) cable (see
Battery Service in the Service and Repairs section of
this chapter).
