Diode Assembly (Serial Number Below 310000000)
ProForce Debris Blowers with a serial number below
310000000 use a diode assembly in the wire harness
(Fig. 23) (see wire harness drawings in Chapter 7 --
Electrical Diagrams). The diode allows the initial current
flow to energize or “wake up” the remote 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 terminal
(see Battery Service in t he Service and Repairs section
of this chapter). 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. 24) 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 t hat secures battery cable from 10
to 15 ft--lb (14 to 20 N--m). Make sure that battery cover
is secured.
