Note. Read the safety precautions in Section 1 of this Chapter.
1. If the starter does not turn on when the key in the ignition switch is turned to the required position, this may be due to the following reasons:
- A) The battery is empty.
- b) There is no connection somewhere between the ignition switch, solenoid, battery and starter.
- V) Solenoid is defective.
- G) The starter has a mechanical or electrical problem.
2. To check the battery, turn on the headlights. If they go out after a few seconds, the battery is low - recharge or replace the battery. If the headlights are bright, turn the key in the ignition and watch the headlights. If their brightness decreases, this means that current is supplied to the starter, and the fault should be sought in it. If the headlights keep burning bright (I can't hear the starter valve solenoid clicking), this indicates that there is an open in the circuit or the solenoid is faulty - see the following paragraphs. If the starter is running slowly and the battery is sufficiently charged, then either the starter is defective or there is high resistance somewhere in the circuit.
3. If you think that the fault lies in the circuit, disconnect the wires from the battery (including wire "masses") and wire "masses" starter/solenoid and engine/gearbox. Thoroughly clean the connections and reattach the wires, then use a voltmeter or test light to check that the positive terminal of the solenoid has battery voltage and is well grounded. Lubricate the battery terminals with petroleum jelly to prevent corrosion - corrosion of connections is one of the most common causes of electrical system failures.
4. If the battery and all connections are in good condition, test the circuit by disconnecting the wire from the solenoid valve terminal. Connect a voltmeter or test light between the end of the wire and ground" car (or negative battery terminal) and check that there is voltage on the wire when the ignition key is turned to the "start". If voltage is present, it means that there are no breaks in the circuit.
5. The solenoid contacts can be checked by connecting a voltmeter or test light between the positive solenoid terminal where the starter wire is connected, and "weight" car. When the key is turned in the ignition switch to position "start", the voltmeter should indicate the presence of voltage or the signal light should light up. If the voltmeter does not show voltage or the light does not light up, then the solenoid is defective and needs to be replaced.
6. If the circuit and solenoid are good, then the starter is the source of the problem. In this case, it is necessary to contact specialists to repair the starter. Check the availability and price of a new starter, as it may be more profitable to buy a new or remanufactured starter instead of repairing the old starter.
