Stop the engine, turn the starter and instrument switch key (SA10) into the position
of instruments on “I”. If the instruments operate – replace the regulating relay of alternator
voltage or alternator itself (the repair shall be carried out by the dealer).
7.15.8.4 When the instruments are on, the starter and instruments SA10 switch key
is in the position “I” and the engine is off, there is no audible beep of alarm signaling
(buzzer).
Check operability of electrical circuits of wire connection to the survival kit relay-
annunciator. In case there is no voltage on the yellow-black wire – restore the circuit integ-
rity. If there is voltage, connect tractor on-board “minus” signal to the second output of the
survival kit relay-annunciator for a short period. If relay-annunciator fails to operate - re-
place the survival kit. If the circuits and the survival kit relay-annunciator operate properly –
replace the combination P2 or send it to the repair shop.
7.15.8.5 The instrument board and integrated indicator lighting does not operate
while marker lights are on.
) If marker lights of the starboard side operate – it indicates that fuse « » (15 ) in the
fuse block F4 is in a good operating order. It is required to check operability of electrical cir-
cuits from the fuse to the instruments 1 and 2. If there are circuit breakages – eliminate
these breakages.
b) If electrical circuits operate properly, replace the corresponding instruments. In
case electrical circuits operate properly, replace the corresponding instruments.
7.15.8.6 The indicator arrow of cooling liquid temperature reads off scale when the
engine is not overheated.
) Check operability of cooling liquid 1 temperature sensor for which it is required
to disconnect the socket from the sensor. If in this case the temperature indicator arrow in
the combination is set above the mark “40° ” – replace the sensor.
b) If the instrument arrow goes on reading off scale after disconnecting the socket
from the sensor, it is required to check the electrical circuit the sensor – indicator for lock-
ing absence in tractor body. If there is locking – eliminate it.
c) In case the circuit operates properly (there is no locking) – replace or send the
combination 2 to the repair shop.
7.15.8.7 The indicator arrow of oil pressure in the engine reads off scale when the
engine lubrication system operates properly.
) Check operability of oil pressure sensor in the engine 1, for which it is required
to disconnect the socket from the sensor and by means of a bonding strip lock the contact
of the socket for tractor “load” for a short period. If the oil indicator arrow is set at the mark
“0” in the combination – replace the sensor.
b) If the instrument arrow goes on reading off scale, it is required to check the elec-
trical circuit sensor – indicator for presence of breakage. If the circuit is broken – eliminate
the breakage.
c) If the circuit operates properly (there are no breakages) – replace or send combi-
nation P2 to the repair shop.
7.15.8.8 The indicator arrow of air pressure in the pneumatic system reads off scale
when the pressure in the pneumatic system is normal.
) Check operability of air pressure sensor in the pneumatic system 3 for which it
is required to disconnect the socket from the sensor and by means of a bonding strip lock
wires in the socket for a short period. If the pressure indicator arrow in the combination is
set at the mark “0” – replace the sensor.
b) If the instrument arrow goes on reading off scale, it is required to check the elec-
trical circuit sensor – indicator for presence of breakage. If the circuit is broken – eliminate
the breakage.
