Check of component ones of the system of cooling Check of a covering of an electric heater
|
|
|
|
-
Install the prover of special bomb in an electric heater covering and, when hail is maintaining it in a not less 30th angle. to the horizon, create the constant pressure, doing one pressing in not less, of what 3 seconds. One secure what over the vacuum valve there passes the air, otherwise substitute a covering of electric heater.
|
- Below the same conditions they create the pressure of 0,9 ÷ 1.2 atm – the security valve has to open. If the valve does not open even in a pressure of 0.75 atm, substitute a covering of electric heater.
|
|
Check holes
|
|
- Fill an electric heater of the cooling of liquid and install the prover of bomb in his mouth. Heat the motor up to the work temperature, create the pressure of 1.2 atm through the bomb and it is secured what does not fall. Otherwise check hoses of system of cooling, an electric heater and the water bomb of the existence of holes. If the extern holes are not, check the conductor of heat of heater, the block and a head of cylinders. Remove holes.

|
Supporters' check
|
|
- The motor begins and the 98th hail is secured of the supporters' connection in the moment of the realization of OZh of the temperature. Otherwise 1 D/V substitutes the ECT n °.
|
|
Check of ECT D/V
|
|
-
Empty the system of cooling and the ECT n withdraws ° 2 and n ° 1 D/V.
|
|
Position of ECT n ° 1 D/V. |
|
|
Position of ECT n ° 2 D/V. |
- Through an ohmmeter they secure the available condutividade between sensors contacts n ° 1 and n ° in a temperature above respectively 98 or 94 I granulate 2. In a temperature there is 88 or 83 I granulate down. respectively for the condutividade n ° 2 and n ° 1 D/V between his contacts has to be going away.
|
|
Measurement of resistance of ECT n ° 1 D/V. |
|
|
Measurement of resistance of ECT n ° 2 D/V. |
- In unsatisfactory checks results they substitute defective D/V.
- Establish D/V, fill the system of cooling of the motor and one secures of the lack of holes.
|
|
Check of the supporters' alternation
|
|
- Take of the block of alternation in a compartment of reason of the alternation n ° 1, n ° 2 and n ° 3 of supporters (to see the electric equipment of Front Side).
- Through an ohmmeter they secure the available condutividade between contacts 3 and 5 each one re-transmits, and also of the lack of the condutividade between contacts of 1 and 2 each one re-transmits. Besides, the condutividade will be between contacts of 2 and 4 alternations n ° 2.
|
|
Contacts of the alternation n ° 1 and n ° 3 of supporters. |
|
|
Contacts of the alternation n ° 2 of supporters. |
- 3 applies the tension of battery to contacts (+) and 5 (-) of each alternation (in series) and one secure the available condutividade between contacts of 1 and 2 each one re-transmits. Besides, below these conditions the condutividade has of 2 is going away between contacts of 2 and 4 alternations n °.
- If the checks produced unsatisfactory results, substitute defective alternations.
