Section 8 Component Troubleshooting
8.1 General
See Figure 8-1 through Figure 8-3 for component
testing.
With the generator set battery connected,
check
the
generator
wiring
harness
and
the
components listed in the following tables. Check each
component using a multimeter to verify that the switches
function and that voltage is present at each component.
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving rotor.
WARNING
Short circuits.
Hazardous voltage/current can cause
severe injury or death.
Short circuits can cause bodily injury
and/or equipment damage
.
Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
Component
Voltmeter Connections
Procedure
Results
Hourmeter and wiring
Connect the red test lead to
the hourmeter positive (+)
terminal. Connect the black
test lead to the hourmeter
negative (--) terminal.
Set the voltmeter to 12 volts
DC or greater. Start the
generator set.
A 12 volt DC reading
indicates the wiring harness
is functional.
None (see Procedure).
Disconnect the hourmeter
leads and apply 12 volts DC
to the hourmeter. The
hourmeter is polarity
sensitive.
If functional, hourmeter
operates.
Stator auxiliary winding B1
and B2
Connect the AC voltmeter
leads to the B1 and B2
windings at connector P11.
Stop the generator set.
Connect a voltmeter to the
B1 and B2 windings. Crank
the generator set and allow
the set to reach rated its
speed.
A reading of 12--15 volts AC
indicates a functional B1/B2
winding.
