Voltmeter Connections
Connect the red test lead to
the hourmeter positive (+)
terminal. Connect the black
test lead to the hourmeter
negative (--) terminal.
None (see Procedure)
Connect the AC voltmeter
leads to the B1 and B2
windings at connector P11.
Stop the generator set.
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.
Procedure
Set the voltmeter to 12 volts
DC or greater. Start the
generator set.
Disconnect the hourmeter
leads and apply 12 volts DC
to the hourmeter. The
hourmeter is polarity
sensitive.
Set the voltmeter setting 20
volts AC or greater. Crank
the generator set and allow
the set to reach rated its
speed.

Results
A 12 volt DC reading
indicates the wiring harness
is functional.
If functional, hourmeter
operates.
A reading of 12--15 volts AC
indicates a functional B1/B2
winding.
