Electrical System
Component Testing
For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplug the ignition switch connector before
doing a continuity check on the ignition switch).
CAUTION
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Fusible Link Harness
The Multi Pro 1750 uses a fusible link for circuit protec-
tion. This fusible link connects the main wire harness to
the starter B+ terminal and positive battery cable. If the
link should fail, current to the machine will cease. Refer
to electrical schematic and wire harness drawings in
Chapter 10 − Electrical Drawings for additional 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 this chapter). Locate and unplug fusible link
connector from machine wire harness. Use a multimeter
to make sure that continuity exists between the discon-
nected fusible link connector and the link terminal at the
starter motor (Fig. 27). If the fusible link is open (no conti-
nuity), 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.
