ground short circuits with 10 A harness fuse. The fuses are
installed into the fuse holder kits, which are fastened as follows:
- 20 A — to the main relay;
- 10 A — to the electric fuel pump relay.
Precautions
1. Prior to dismantling and installation of any components or
wires of the control system, disconnect the rechargeable battery
ground wire.
2. The engine may not be started if the rechargeable battery
is connected unreliably.
3. The rechargeable battery may not be disconnected from
the vehicle's electrical network while the engine is running.
4. If being charged from the external source, the rechargeable
battery must be disconnected from the vehicle's electrical network.
5. The control unit may not be exposed to temperatures above
80°C, e.g., in an oven dryer.
6. Prior to arc welding operations, disconnect the battery
wire and the control unit connector.
7. To prevent rusting of pins during vapor cleaning, do not
direct the nozzle towards system components.
8. The electronic components of the control systems are
designed for very low voltage and are vulnerable to electrostatic
discharges.
9. The fuel system, at the section from the fuel priming
pump to the fuel pressure controller on the running engine, is
pressurized to 3.8 kgf/cm2.
To prevent leaking of fuel, check thoroughly the hermetic-
tightness of the pipeline joints. The check shall be carried out
with sufficient lighting and the engine running idle.
The threaded joints leaks shall be eliminated through tightening
of nuts and nozzles by a wrench with moderate force ensuring
hermetic-tightness.
The fuel line joints may not be loosened with the engine
running or immediately after it stops.
10. To avoid fuel priming pump failure, it may not be switched
on dry, when there is no fuel in the right-side tank.
11. The engine, in which low-voltage wires to the ignition
coils are installed improperly, may not be started. The branch of
wires to the ignition coils must be connected in series, starting
from the first cylinder.
