Note. See warnings. contained in paragraph 1 of this chapter before starting work.
1. If the starter refuses to work when the ignition key is turned to the appropriate position, there can be many reasons for this.
- A) "ran out" battery.
- b) The electrical connections are broken to move the current of the required amount from the battery through the starter, to the car body - back to the battery.
- V) Faulty solenoid relay.
- G) Starter motor defective - electrically or mechanically.
2. To check the battery, turn on the headlights. If they fade after a few seconds, the battery is low. Charge or replace the battery (see paragraph 2).If the headlights are bright, turn on the starter and observe the lamps. If the light dims, this indicates that electrical current is reaching the starter motor, which means that the fault is hidden in the starter. If the headlights stay bright (I can't hear the click of the starter relay), this indicates a malfunction in the circuit or solenoid - see the following points. If the starter motor turns the engine weakly, but the battery is in good condition, this indicates a malfunction of the starter motor or increased resistance in the circuit.
3. If there is a suspicion of a circuit malfunction, disconnect the battery wires (included wire going to the body), retractor relay wiring and a thick wire from the engine block to the body. Thoroughly clean all connections and restore them. then use a voltmeter or light bulb to check for the presence of full battery voltage on the positive wire" negative wire. Lubricate the battery terminals with grease to prevent corrosion - the whole trouble is in bad contacts.
4. If the battery and all contacts are in good condition, check the circuit by disconnecting the wire from the retractor. Attach a test lamp between the removed wire and 'ground' - bare metal on the body or the negative terminal of the battery and make sure that the wire is intact. when you turn on the ignition. If the test light is on, then the circuit is intact, unless you check the circuit as described in chapter 12.
5. The solenoid relay contacts can be checked by attaching a voltmeter or test light between the positive wire where it is connected to the starter motor and "weight". If you turn on the starter, the lamp should be on or there should be a corresponding voltage on the voltmeter indicator. If not, the solenoid relay is faulty and should be replaced.
6. If the circuit and solenoid relay are OK, the starter motor may be faulty. It is better to give it to specialists for repair, but first ask about the cost of repairs, it may be cheaper to buy a new or remanufactured starter.
