7-14 Component Testing and Adjustment TP-5606 6/02
Engine/Generator Components
With the generator set battery connected, the wiring
harness and some engine/generator components can
be checked with a voltmeter as described in
Figure 7-12. Place the controller or remote start/stop
switch in the prescribed position and check for 12 volts
DC at each component using a DC voltmeter. This will
verify that the switches function and 12 volt DC is
present at each component.
Component
Voltmeter Connections Remarks Results
Hourmeter and
wiring
Red test clip to hourmeter
(+) terminal. Black test clip
to (--) terminal.
Voltmeter setting 12 volts. If wiring harness is
good--12 volts DC or
greater. To determine if
hourmeter is good, proceed
to next step.
None (see Remarks) Disconnect hourmeter
leads and apply 12 volts
DC to hourmeter.
If good--hourmeter will
operate.
NOTE: Hourmeter is
polarity sensitive.
B1 and B2 stator
auxiliary winding
Disconnect B1/B2 leads.
Connect AC voltmeter to
leads.
NOTE: Voltage can only be
measured momentarily
since unit will not continue
to run after start switch is
released.
Voltmeter setting 20 volts
AC or greater. Start
generator set by holding
Start/Stop switch in Start
and allow to reach proper
speed. Take reading and
then stop generator.
Reading of 12--15 volts
indicates B1/B2 winding is
good.
Fuel solenoid
(three-lead)
Red test clip to #6 lead of
solenoid and black test clip
to engine block (ground).
Place controller switch to
Start position. STOP
generator set.
Voltmeter setting 12 volts or
greater. If lead can not be
disconnected, cut leads
and crimp-on fully insulated
push-on terminals.
If wiring is good--12 volts
DC. To determine if fuel
solenoid is good, proceed
to next step.
None (see Remarks) Push out leads #6 and “P”
at the 4-pin connector.
Apply 12 volts DC to #6
lead and momentarily apply
12 volts DC to “P” lead.
NOTE: Apply voltage only
momentarily to “P” lead to
prevent fuel solenoid
damage. This coil draws 50
amps and is intended only
to energize the solenoid.
If good--fuel solenoid will
energize and move plunger
when voltage is applied to
“P” lead and remain
held in after “P” lead is
disconnected as long
as #6 lead has voltage
appliedtoit.
