Diode Assembly
A diode assembly (Fig. 42) is used in the Groundsmas-
ter 4300--D engine wire harness. The diode is used for
circuit protection from voltage spikes that occur when
the engine starter solenoid is de--energized. Refer to
wire harness drawings in Chapter 8 -- Foldout Drawings
for additional diode assembly information.
Testing
Locate diode assembly and remove cable tie that se-
cures diode to wire harness. Unplug the diode from the
wire harness for testing. The diode (Fig. 43) can be
tested using a digital multimeter (diode test or ohms s et-
ting) and the table below.Aftertestingiscomplete,make
sure that diode is fully installed into harness connector
and secured to harness with cable tie.
