Component Testing
Whenever possible, check component circuit operation
with the InfoCenter Display on the console. With the key
switch in the RUN position, use the InfoCenter Diagnos-
tics menu to make sure that the component state
changes as the component is toggled. This quick check
identifies that thecomponentandcircuitwiring are work-
ing as designed. If the InfoCenter operation suggests
that a component circuit is n ot functioning correctly, pro-
ceed to the appropriate component testing procedure
found in this section. If the test procedure identifies no
problem with the component, carefully inspect the wire
harness and connectors for problems.
The Greensmaster eFlex uses a 53 volt DC (nominal)
electrical system that is an isolated circuit. The vehicle
frame is not used for any ground connections.
For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplugthe ON/OFF switch connector before
doing a continuity check on switch). Individual compo-
nents should be electrically isolated (e.g. disconnect all
leads or remove from circuit) from the circuit when
tested.
When testing a machine electrical component
for continuity with a multimeter (ohms setting),
makesurethatcomponentis disconnected from
machine wire harness to prevent current flow
through the component.
CAUTION
CAUTION
Remove all jewelry, especially rings and
watches, before doing any electrical t rouble-
shooting or testing. Disconnect the lithium bat-
tery pack to open the battery circuit before work-
ing on the electrical system.
