Electrical equipment
AB has low charge degree
Low level of voltage being regulated Replace generator voltage regulator.
High contact resistance between storage
battery terminals and wiring tips due to
loosening and oxidation
Dress connection terminals, tighten and
non-contact elements with technical cup
grease. Tighten fastening of “ground”
switch and “ground” junction.
Faulty generator (no voltage on terminals
“+” and “D”
1. Replace generator voltage regulator
2. Dismount the generator and send to
workshop for repair.
Faulty storage battery.
Replace the battery.

High level of voltage being regulated
Replace generator voltage regulator.
Faulty AB.
Replace the battery.

Poor tension of storage battery terminals,
or oxidation of wiring tips.
Dress tips and tighten terminals
Storage battery discharged below allowable
limit
Charge or replace storage battery
Poor contact of brushes with collector
Dismount starter from diesel, dress the
collector, correct hang up of brushes or
replace them, if they are worn out
Slippage of starter drive coupling (wear
of coupling or shell cracking).
Replace starter drive.
Diesel start locking device is actuated, its
switch is defective
Shift GB levers to neutral position, check
switch serviceability. If necessary, adjust
switch position with adjusting washers.
Diesel is not made ready for start at low
temperature below +5
0
C
Get diesel ready for start at low tempera-
tures
After diesel start starter remains in the engaged position
Stuck contacts of control starter relay
using(installed in the instruments panel)
Stop the diesel and switch off SB “ground”
switch. Send starter and relay to workshop
for repair.
Power disk is welded to contact bolts of
starter relay
Shut down diesel. Send starter for repair
Driving pinion doesn’t disengage the fly-
wheel ring gear due to breakage of shifter
lever spring
Shut down diesel. Send starter to
workshop for repair
