TROUBLESHOOTING THE CONTROL (Continued)
Many troubleshooting procedures present hazards which can result in severe personal injury or
-1
death. Only qualified service personnel with knowledge of fuels, electricity, andmachineryhazards
should perform service procedures. Review

TROUBLE
Run Lamp, Time
Meter,
or
Battery
Condition Meter
Inoperative
Generator Set
Does Not Stop
After Start/Stop
Switch
Is
Pushed
to
Off
Position
(Note:
Always
remove
load
a
few minutes
before stopping
to
allow set
to
cool
down.)
POSSIBLE CAUSE
1.
Open circuit between terminal
6
on remote connector plug and
terminal
6
on remote start/stop
switch.
2.
Open circuit between ground
terminals on lamp
or
meters
and terminal
1
on remote start/
stop switch and remote connector
terminal
1.
3. If battery condition meter
works but time meter does not
operate, time meter is defective.
4. If time meter works but battery
condition meter does not operate
verify that jumper wire is
connected between terminals
5
and
6
on remote start/stop
switch. If jumper is in place,
connect a voltmeter between
the positive terminal on
battery charge meter and ground.
Use the following
to
determine
fault:
a.
If
reading equals battery
voltage minus
10
volts,
battery meter is defective
b.
if
reading does not equal
battery voltage minus
10
volts, zener diode in remote
control is defective.
1.
Faulty set control start/stop
switch
(SI)
2.*K5 relay not energizing due
to:
a. open circuit
to
K5 relay coil
b. faulty K5 relay
3.*K4 solenoid not energizing due
a. open circuit
to
K4 solenoid
a. faulty K4 solenoid
to:
4.*K4 solenoid
out
of adjustment.
5.
Defective K3 relay contacts
*Gasoline sets only
CORRECTIVE ACTION
~~
1.
Check for continuity and correct if
circuit is open.
2.
Check for continuity and correct if
circuit
is
open.
3. Replace time meter.
4a. Replace battery condition meter.
4b. Replace zener diode.
1.
Check start/stop switch and replace
if defective.
2a. Check for continuity and correct
if
circuit is open.
2b. Check K5 relay coil
(85
rt5ohms) and
contacts, replace
if
defective.
3a. Check for continuity and correct
if
3b. Replace K4 solenoid.
circuit is open.
4. Adjust K4 solenoid mounting bracket
sc
solenoid causes governor arm to
completely close throttle when energizr
5.
Gasoline-fueled sets: Check normally-
closed contacts K3-30/K3-87A, replacc
relay
if
defective.
LPG fueled sets: Check K3 relay coil ai
K3 normally-open contacts K3-30/K3-I
replace relay if defective.
Nole:
A
ballast resistor
(R2)
is
used inline with the fuel pump to reduce the voltage toapproximately9volts. to increase pump life. During cranking,
the ballast resistor is bypassed through diode
CR3
for
low
voltage operation
of
the pump. Resistor
R2
and diode
CR3
are not used in later
production sets.
