Continuation of Table 3
Trouble and its appearance Remedy
the storage battery terminals
b) The storage battery is discharged or
faulty
Recharge or replace the storage battery
c) Scale of the RS-502(Sh) switch contacts Clean the contacts
d) Failure in the starter solenoid switch
circuit
Check the circuit and eliminate the failure
8.2 When switching on the starter the in-
creased noise of the driving gear is
heard
Clean the teeth from the burrs and nicks, replace
the flywheel rim or driving gear
8.3 When being switched on, the starter
does not turn the crankshaft or rotates
too slowly:
a) The storage battery is discharged below
the allowable limit
Recharge or replace the storage battery
b) The collector and brushes are dirty Clean the collector and brushes
c) Scale on the starter solenoid switch
contacts
Clean the starter solenoid switch contacts
d) Slip of the starter driving clutch (wear
and tear of the clutch rollers or crack in
the holder)
Replace the starter drive
8.4 After starting the diesel engine the
starter keep running
Stop the diesel engine, disconnect the storage
battery and clean the starter solenoid switch con-
tacts
8.5 The driving gear does not disengage
from the flywheel rim due to breakage
of the restoring spring of the drive re-
tracting lever
Replace the restoring spring

Alternator
9.1 The alternator provides no recharge of
the storage battery:
a) Ground fault of the stator phase wind-
ing
Remove the alternator from the engine, insulate
the place of the insulation damage
b) Break of the winding lead Remove the alternator from the engine, solder
and insulate the break point; if necessary, replace
the winding
9.2 The alternator does not provide the full
capacity
a) Slippage of the driving belt Adjust the driving belt tension
b) Break of one of the stator windings Remove the alternator from the engine, solder
and insulate the break point; if necessary, replace
the winding
c) Interturn short circuit in the excitation
winding
Replace the winding
9.3 Considerable decrease of the controlla-
ble voltage
Replace the voltage regulator
9.4 The storage battery becomes systemati-
cally overcharged (ammeter shows
large charging current and, in the ab-
