3.1.2. Malfunctions in start-up system
Malfunctions in system of start-up are shown in abnormal work of a starter. It is possible to allocate five main malfunctions of a starter.
1. The starter does not join. The reason — a safety lock peregoraniye in the block of power safety locks established in podkapotny space, violation of contact connections, break or short circuit in chains of inclusion of a starter, malfunction of the traction relay.
2. At inclusion of a starter repeated clicks are audible. The reason — malfunction of a holding winding of the traction relay, is strongly discharged the storage battery, contact connections in a starter chain are weakened.
3. The starter joins, but its anchor either does not rotate, or rotates slowly. The reason — is discharged the storage battery, contact connections are broken, contacts of the traction relay burn slightly, the collector is polluted or brushes, mezhvitkovy or short circuit in windings are worn-out.
4. The starter joins, its anchor rotates, but the flywheel remains motionless. The reason — weakening of fastening of a starter to a coupling case, damage of teeths of a flywheel or a drive gear wheel, pro-slipping of the coupling of a free wheeling of a drive, breakage of the lever, a freshet ring or a buffer spring of a drive of a starter.
5. The starter is not switched off after engine start-up. The reason — malfunction of the coupling of a free wheeling of a starter, agglomeration of contacts of the traction relay. In case of such malfunction immediately stop the engine!
The specified malfunctions demand the qualified intervention on car-care center or after arrival to garage (see section 10 "Electric equipment"). Previously it is possible to check only degree of a razryazhennost of the storage battery by means of the additional voltmeter (for example, a part autotester) and an inhaling of contact connections in a starter chain.
