3.1.2. Malfunctions in start-up system
Malfunctions in start-up system are shown in abnormal work of a starter. It is possible to allocate five basic malfunctions of a starter.
1. The starter does not join. The reasons — infringement of contact connections, breakage or short circuit in chains of inclusion of a starter, malfunction of the traction relay.
2. At starter inclusion repeated clicks are audible. The reasons — the keeping winding of the traction relay is faulty, the storage battery is strongly discharged, contact connections in a starter chain are weakened.
3. The starter joins, but its anchor either does not rotate, or rotates slowly. The reasons — the storage battery is discharged, contact connections are broken, contacts of the traction relay have burnt slightly, the collector is polluted or brushes, межвитковое or short circuit in windings are worn out.
4. The starter joins, its anchor rotates, but the flywheel remains motionless. The reasons — easing of fastening of a starter to картеру couplings, damage of teeths of a flywheel or a drive gear wheel, proslipping муфты a free wheeling of a drive, lever breakage, поводкового a ring or a buffer spring of a drive of a starter.
5. The starter is not switched off after engine start-up. The reasons — malfunction муфты a starter free wheeling, sintering of contacts of the traction relay. In case of such malfunction immediately stop the engine!
The specified malfunctions demand the qualified intervention in car-care centre or after arrival to garage (section 10 "Electric equipment" see). It is preliminary possible to check up only degree разряженности the storage battery by means of the voltmeter (for example, as a part of an autotester) and an inhaling of contact connections in a starter chain.
