Electrical System
Diode Assembly
A diode assembly (Fig. 11) is used in the ProForce De-
bris Blower wire harness (see wire harness drawings in
Chapter 7
−
Electrical Diagrams). The diode provides
the initial current flow to energize or “wake up” the re-
mote control module.
Testing
1. Make sure that ignition switch is OFF.
2. To prevent unexpected machine operation, discon-
nect the negative battery cable from the battery termi-
nal. Position disconnected negative cable away from
the negative battery terminal.
3. Locate diode assembly and remove cable tie that se-
cures diode to machine wire harness.
4. Unplug the diode from the wire harness for testing.
5. The diode (Fig. 12) can be tested using a digital
multimeter (diode test or ohms setting) and the table in
the right column.
6. After testing is complete, make sure that diode is fully
installed into machine wire harness connector and se-
cured to harness with cable tie.
7. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from
10
to 15 ft

. Make sure that battery cover
is secured.
